3,6-Dibromo-9H-carbazole Certified Reference Standard

    

Halogenated carbazoles have recently been recognised as emerging environmental contaminants. Although there exact source has not been determined, both modern and historic sources (LED manufacturing and halogenated indigo dyes respectively) have been suggested. Since certain halogenated carbazole congeners can be lost during acid silica clean-up, it is very important that reference standards be used to monitor recoveries when processing samples.

Halogenated carbazoles have recently been detected in soil and water samples, but their environmental effects and fate are unknown. Eighty-four soil samples obtained from a site with no recorded history of pollution were used to assess the persistence and dioxin-like toxicity of carbazole and chlorocarbazoles in soil under controlled conditions for 15 months. Soil samples were divided into two temperature conditions, 15 and 20 °C, both under fluctuating soil moisture conditions comprising 19 and 44 drying-rewetting cycles, respectively. This was characterized by natural water loss by evaporation and rewetting to -15 kPa. Accelerated solvent extraction (ASE) and cleanup were performed after incubation. Identification and quantification were done using high-resolution gas chromatogram/mass spectrometer (HRGC/MS), while dioxin-like toxicity was determined by ethoxyresorufin-O-deethylase (EROD) induction in H4IIA rat hepatoma cells assay and multidimensional quantitative structure-activity relationships (mQSAR) modelling. Carbazole, 3-chlorocarbazole and 3,6-dichlorocarbazole were detected including trichlorocarbazole not previously reported in soils. Carbazole and 3-chlorocarbazole showed significant dissipation at 15 °C but not at 20 °C incubating conditions indicating that low temperature could be suitable for dissipation of carbazole and chlorocarbazoles. 3,6-Dichlorocarbazole was resistant at both conditions. Trichlorocarbazole however exhibited a tendency to increase in concentration with time. 3-Chlorocarbazole, 3,6-dibromocarbazole and selected soil extracts exhibited EROD activity. Dioxin-like toxicity did not decrease significantly with time, whereas the sum chlorocarbazole toxic equivalence concentrations (∑TEQ) did not contribute significantly to the soil assay dioxin-like toxicity equivalent concentrations (TCDD-EQ). Carbazole and chlorocarbazoles are persistent with the latter also toxic in natural conditions.

 Why filter your samples for HPLC?

 • To protect the HPLC column, the column inlet frits and capillary columns against blockage (plugging) caused by particulate matter in the sample

• To protect injection valves from damage caused by scratching and wear of the valves internal components, caused by harmful particulate matter in the unfiltered sample, thereby reducing instrument downtime.

   About our Quality Control procedures

 • Every batch of filters is tested by an independent laboratory to ISO 17025 quality procedures

 • Every individual Q-Fil Certified Syringe Filter is visually inspected to ensure it meets our manufacturing and quality control specifications

• Samples of all our syringe filters and their respective raw technical data are stored for a period of 5 years from the date of manufacture for future reference
• Each batch of filters is tested prior to release for
- External Dimensions
- Bubble Point
- Burst Pressure
- Filter Integrity
- Water Flow Rate
- UV Extractables and compliance with all technical procedures

   Why use Greyhound Q-Fil Certified Syringe Filters?

 • Q-Fil Certified Syringe Filters are manufactured in compliance with ISO 9001:2000 quality procedures

 • Every box is supplied with a Certificate of Analysis and Conformance to guarantee its batch to batch quality and performance

• The unique encapsulating process developed for these filters, forces the sample to pass only through the membrane, thus avoiding the possibility of leaks or contamination
• Available in the most popular sizes, porosities and membrane types
• Excellent resistance to all routinely used HPLC solvents
• Filter housings are manufactured from high density medical grade polypropylene
• Extremely low level of extractables for highly sensitive work
• Luer connections fully comply with ISO 594-1
• Filters are available with standard and ‘SlimTip’ sized outlets

   Selecting the right Q-Fil Certified Syringe Filter

 • Choose the size of filter based on the volume of sample to be filtered

 • Choose the filters porosity based on the size of the potential particulates in the sample. It is important to be aware that the finer the porosity of the membrane the greater the pressure will be required to pass the sample through the filter. A sample containing large quantities of particulates is best filtered using a filter with a built-in glass fibre pre-filter

• Choose the type of membrane based on the solvent being filtered.

 Filter Sizes

 All our filters have female Luer Lock inlets and are available in three diameters -

 25mm Diameter

Designed for large sample volumes or solvent filtration
Wide cross sectional area 3.55cm2
Maximum filtration volume >10ml
Maximum operating pressure 550 Kpa

 13mm Diameter

Suitable for most applications
Filtration area of 0.95cm2
Maximum filtration volume 1 to 10ml Maximum operating pressure 750 Kpa Now available with ‘SlimTip’ (ST) outlet

 4mm Diameter

Suitable for most applications Ideal for small samples <1ml Pore sizes of 0.20µm and 0.45µm
SlimTip Filters (ST)
13mm diameter syringe filters are now available with the new ‘SlimTip’ outlet for direct filling of microvials.

 Pore Sizes

 Q-Fil Certified Syringe Filters are available in 0.20µm and 0.45µm pore sizes. The 0.20µm filters remove the smallest particulates whilst the 0.45µm filters are designed to remove particulates which would be detrimental to most analytical columns.

 Pre-filters (page 6) have a glass microfibre membrane which is chemically inert and resists most solvents. Q-Fil glass microfibre pre-filters are recommended for removing large particulates from the sample and are ideal for dissolution tests.

 Glass microfibre membranes are also available mounted before the microporous filter membrane in the polypropylene housing. The glass pre-filter removes the larger particulates and prevents premature clogging of the filter.

 Why filter your samples for HPLC?

 • To protect the HPLC column, the column inlet frits and capillary columns against blockage (plugging) caused by particulate matter in the sample

• To protect injection valves from damage caused by scratching and wear of the valves internal components, caused by harmful particulate matter in the unfiltered sample, thereby reducing instrument downtime.

   About our Quality Control procedures

 • Every batch of filters is tested by an independent laboratory to ISO 17025 quality procedures

 • Every individual Q-Fil Certified Syringe Filter is visually inspected to ensure it meets our manufacturing and quality control specifications

• Samples of all our syringe filters and their respective raw technical data are stored for a period of 5 years from the date of manufacture for future reference
• Each batch of filters is tested prior to release for
- External Dimensions
- Bubble Point
- Burst Pressure
- Filter Integrity
- Water Flow Rate
- UV Extractables and compliance with all technical procedures

   Why use Greyhound Q-Fil Certified Syringe Filters?

 • Q-Fil Certified Syringe Filters are manufactured in compliance with ISO 9001:2000 quality procedures

 • Every box is supplied with a Certificate of Analysis and Conformance to guarantee its batch to batch quality and performance

• The unique encapsulating process developed for these filters, forces the sample to pass only through the membrane, thus avoiding the possibility of leaks or contamination
• Available in the most popular sizes, porosities and membrane types
• Excellent resistance to all routinely used HPLC solvents
• Filter housings are manufactured from high density medical grade polypropylene
• Extremely low level of extractables for highly sensitive work
• Luer connections fully comply with ISO 594-1
• Filters are available with standard and ‘SlimTip’ sized outlets

   Selecting the right Q-Fil Certified Syringe Filter

 • Choose the size of filter based on the volume of sample to be filtered

 • Choose the filters porosity based on the size of the potential particulates in the sample. It is important to be aware that the finer the porosity of the membrane the greater the pressure will be required to pass the sample through the filter. A sample containing large quantities of particulates is best filtered using a filter with a built-in glass fibre pre-filter

• Choose the type of membrane based on the solvent being filtered.

 

Filter Sizes

 All our filters have female Luer Lock inlets and are available in three diameters -

 25mm Diameter

Designed for large sample volumes or solvent filtration
Wide cross sectional area 3.55cm2
Maximum filtration volume >10ml

 4mm Diameter

Suitable for most applications Ideal for small samples <1ml Pore sizes of 0.20µm and 0.45µm
SlimTip Filters (ST)
13mm diameter syringe filters are now available with the new ‘SlimTip’ outlet for direct filling of microvials.

Pore Sizes

 Q-Fil Certified Syringe Filters are available in 0.20µm and 0.45µm pore sizes. The 0.20µm filters remove the smallest particulates whilst the 0.45µm filters are designed to remove particulates which would be detrimental to most analytical columns.

 Pre-filters (page 6) have a glass microfibre membrane which is chemically inert and resists most solvents. Q-Fil glass microfibre pre-filters are recommended for removing large particulates from the sample and are ideal for dissolution tests.

 Glass microfibre membranes are also available mounted before the microporous filter membrane in the polypropylene housing. The glass pre-filter removes the larger particulates and prevents premature clogging of the filter.

PFAS and Other Toxic Forever Chemicals in Drinking Water 

For over 30 years the European Union have worked tirelessly to protect the integrity of our drinking water.  EU officials have recently reached a provisional agreement to update the Union's 1998 Drinking Water Directive to tighten up the permissible limits allowed for both PFAS and several other drinking water contaminants, including bisphenol-A, microplastics, lead and chromium.   The at the time of writing the European Parliament and Council are still to formally approve the proposal. 

European drinking water standards currently far exceed the standards set in the United States but this is a changing picture as state by state new instances of contaminants are emerging.  Currently, the U.S. Environmental Protection Agency has only issued a nonenforceable health advisory of 70 ppt for PFOA, formerly used by DuPont to make Teflon, and PFOS, formerly an ingredient in 3M’s Scotchgard. Those compounds are no longer manufactured in the U.S., but they and other PFAS contaminate the drinking water for an estimated 110 million Americans. PFOA, PFOS and some other PFAS chemicals have been linked to cancer, thyroid disease, reproductive and immune system problems, and other health harms.

The european Parliament and the Council of the European Union have released new requirements for the analysis of per- and perfluoroalkyl substances (PFAS) in water intended for human consumption (5813/20).  This amendment to Council Directive 98/83/EC included perfluoroalkanesulfonates that are not commercially available.  In response to this Wellington Labroatories, Canada, is pleased to announce that its chemists have synthesized, purified, characterized and prepared accurate certified reference standards of the required substances: sodium perfluoro-1-undecanesulfonate (L-PFUds) and sodium perfluoro-1-tridecanesulfonate (L-PFTrDS).  Wellington Laboratories have also prepared a native solution/mixture (EU-5813-NSS) that contains all of the PFAS listed in the drinking water directive (5813/20) for your convenience.  This solution/mixture can be used in conjunction with two of Wellington's existing mass-labelled PFAS mixtures to easily prepare a calibration set for quantification. 

Suggested extraction standard mixture :  MPFAC-C-ES

Suggested injection standard mixture:     MPFAC-C-IS
