The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide. While providing an ultra wide range of 4 μg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 μg/L through coordination with NDIR. This is the highest level of detection sensitivity

The term "semi-volatile compounds" refers to organic compounds that possess Henry’s law constants (H) in the range of 10 -5 - 3 x 10 -7 atm*m 3 /mol* and demonstrate higher boiling points, usually greater than that of water with correspondingly low vapor pressure from 10 -14 - 10 -4 atm. *H range defined as volatility from liquid to air.

2022年5月19日 · ESS (San Leandro, California) conducted an internal trip blank study in 2018. Seventy-two EPA vials were filled to zero headspace with medium cap tightness. After two weeks in refrigeration, only one vial had an air bubble of greater than six millimeters. Those vials were removed from refrigeration and stored at room temperature.
