Environmental Grade - Alfa Aesar

Environmental Grade

Environmental grade solvents are specially made for trace environmental analysis. These solvents have extremely low levels of trihalomethanes, organohalides and organic hydrocarbon residue. The extremely low level impurities results in a clean baseline and increases the sensitivity of detection to pictogram level.

Environmental grade solvents are used for the trace analysis of polyaromatic hydrocarbons, pesticides, protecting agents of stored goods and plants etc. The detection of these trace level compounds is important as many of them are toxic or mutagenic in nature and causes concern to environment.

These solvents can be directly used in HPLC and GC instruments by using UV, Fluorescence, FID, ECD, MS & NPD detectors.
