ISO/DIS 9377Water Quality Testing
(German H-53)
Reference mixtures for ISO/DIS 9377 (German H-53), a gas
chromatography–flame ionization detection (GC-FID) method.
Standard Mixture Stock Solution
(2 components)
• For GC analysis of total petroleum hydrocarbons (TPH)
in water.
• Calibration standard available as Diesel #2/motor oil and
Diesel #2/mineral oil.
500 µg/mL each in acetone, 1 mL/ampul (1 mL is enough mix to spike one 900 mL quality
control sample). Total hydrocarbon concentration is 1,000 µg/mL.
cat.# 31641 (ea.)
Diesel #2 (additive-free) (68334-30-5)
Motor oil (additive-free bp 325–460 or C18–C32 retention time range) (64742-65-0)
Quality Control Standard Mixture, Revised
(2 components)
• Updated reference materials for GC analysis of TPH in water.
• Determination of hydrocarbon oil index—applicable to
drinking, surface, waste, and treated water.
500 µg/mL each in acetone, 1 mL/ampul (1 mL is enough mix to spike one quality control
sample). Total hydrocarbon concentration is 1,000 µg/mL.
cat.# 31631 (ea.)
Diesel #2 (additive-free) (68334-30-5)
Mineral oil (additive-free [i.e., USP grade] bp 391–522 or C24–C40 retention time range)
(8042-47-5)
Quality Control Standard Mixture
(2 components)
• For GC analysis of total petroleum hydrocarbons (TPH)
in water.
• Environmentally safer than previous methods.

(7 components)
Drinking Water Odor
100 µg/mL in P&T methanol, 1 mL/ampul
cat.# 30608 (ea.)
(+/–)-Geosmin (16423-19-1)
2-Methylisoborneol (MIB) (2371-42-8)
DrinkingWater Odor Standard
(2 components)
• Reference mix of the two most common odor-causing
compounds.
• Convenient concentration for purge-and-trap analysis:
100 µg/mL in methanol.
Unpleasant odor in drinking water is associated with the
growth and decay of microorganisms. The threshold value for
these compounds is low (10 ppt), and purge-and-trap analyses
usually are used to quantify them.
Ethylene Oxide

cat.# 36005 (ea.)
50 mg/mL in methylene chloride, 1 mL/ampul
cat.# 30620 (ea.)
