Forensic Ethanol Standards
✔ 0.08g/dL standard supports new federal blood alcohol limit.
✔ 0.4g/dL standard supports autopsy of alcohol-related deaths.
✔ 0.05g/dL standard supports limits for long-haul truck drivers.
✔ Many other concentrations available.
The United States’ blood alcohol limit has been reduced to 0.08g/dL. Consistent with our commitment to sup-
port police and crime laboratories, we are introducing three new reference mixes to meet current needs.
Restek Forensic Ethanol Standards are NIST traceable. Data packs included.
Carbazole
✔ No interference with OLC 03.2 target compounds.
Many laboratories following US EPA Contract
Laboratory Program OLC 03.2 Statement of Work
also analyze for carbazole. Most carbazole reference
solutions are in methanol, but certain target com-
pounds in OLC 03.2 SOW react with methanol (e.g.,
benzaldehyde, atrazine). We prepare our new refer-
ence standard in methanol-free methylene chloride,
to prevent reactions when it is added to OLC 03.2
Semivolatile MegaMix™ (cat.# 31812).
ε-Caprolactam
A precursor in the synthesis of nylon-6, ε-caprolac-
tam is one of the most heavily and widely used
chemical intermediates—more than 9.5 billion
pounds each year, worldwide. Environmental con-
tamination should be anticipated, and caprolactam
has toxic effects. This solution is suitable for moni-
toring ε-caprolactam.
Glyphosate and AMPA (glyphosate
metabolite)
✔ Glyphosate packaged in two volumes, to meet
varied requirements.
✔ Glyphosate at 1000µg/mL concentration, for
more analyses per ampul.
Glyphosate (N-phosphonomethyl glycine) is a broad-
spectrum post-emergence herbicide used in agricul-
ture and forestry and for aquatic weed control. A
weak organic acid, glyphosate usually is formulated
as the isopropylamine salt to increase solubility. Our
new mix is suitable for EPA Method 547, for identify-
ing and measuring glyphosate in drinking water
(HPLC with fluorescence detection and post-column
derivatization).
Aminomethylphosphonic acid—AMPA—is the pri-
mary degradation product of glyphosate in plants,
soil, and water. The chemical structures of the two
compounds are very similar, and they have similar
toxicological profiles. The health base value for
glyphosate also applies to AMPA, and to glyphosate
and AMPA in combination.
PCB-Free Transformer Oil
✔ Convenient 5mL and 50mL packaging.
Use and disposal of all mineral oil-filled transform-
ers have been subject to federal regulation since
1978. Traditionally, transformer oil is tested for poly-
chlorinated biphenyls (PCBs) contamination by GC.
Acrolein & Acrylonitrile
✔ High concentrations:
acrolein: 10,000µg/mL
acrylonitrile: 2,000µg/mL
acrolein/acrylonitrile: 2,000µg/mL.
Acrolein and acrylonitrile are monomers used in
manufacturing polyacrylamide and other acrylic
polymers. These new mixes are suitable for use with
US EPA Method 603, or other methods for testing
water samples for acrylonitrile and acrolein by purge
& trap GC. They have a shelf life of 2-3 months.
