ASTM International has released the following LC/MS/MS water standards:

• D7598 Analysis for Thiodiglycol (LC/MS/MS)
• D7599 Analysis for Ethanolamines (LC/MS/MS)
• D7600 Analysis for Carbamates (LC/MS/MS)
• D7645 Analysis for Carbamates (LC/MS/MS)

D7598 Analysis for Thiodiglycol in Water (LC/MS/MS)
Method D7598 applies to Thiodiglycol, a compound used in the manufacture of chemical weapons, insecticides, inks, lubricants and pharmaceutical products. The Method has been designed for surface water analysis, and includes the target compound and surrogate standard.
 

ASTM Thiodiglycol Standard
D-75981 mL
4 mg/mL in Methanol1 comps.

Thiodigylcol

 

ASTM Thiodipropanol Standard
D-7598-SS1 mL
4 mg/mL in Methanol1 comps.

3,3'-Thiodipropanol

D7599 Analysis for Ethanolamines in Water (LC/MS/MS)
ASTM Method D7599 describes the qualitative and quantitative analysis of ethanolamine compounds - Diethanolamine, Triethanolamine, N-methyldiethanolamine and N-ethyldiethanolamine in surface waters. These compounds are listed as Schedule 3 chemicals under the Chemical Weapons Convention due to their toxicity and other properties that could potentially render them components of chemical weapons. In industry, these chemicals have a broad range of applications including the production of adhesives, detergents, inks, pesticides and pharmaceuticals.

ASTM Ethanolamine Standard
D-75991 mL
50 µg/mL in Methanol5 comps.

Diethanolamine

N-Methyldiethanolamine

Diethanolamine-d8

 

ASTM Ethanolamine Surrogate Standard
D-7599-SS1 mL
50 µg/mL in Methanol1 comps.

Diethanolamine-d8

D7600 and D7645 Carbamate Water Methods
ASTM Methods D7600 and D7645 apply to the analysis of carbamate pesticides in surface waters. The biological affect and residual risk of these compounds is on the nervous system through enzyme inhibition. However, residual levels of these compounds in water are unlikely to cause a cumulative effect in most aquifers.
