149 Results for: "gas chromatography solvents"

Supplier: Honeywell Research Chemicals

B&J GC2 Solvents are developed for trace analysis at or below the part-per-billion level, using capillary gas chromatography. Each lot is performance tested to meet demanding GC specifications.

Samples of every B&J GC2 solvent are concentrated 1000-fold and tested by temperature-programmed capillary GC-FID. This analysis detects both low-boiling and high-boiling molecules, anything eluting from toluene through diesel fuel and other semi-volatile compounds of environmental interest.

Features:
Less than 1 ppb trace contamination for semi-volatiles with a molecular weight greater than toluene (92).
Ideal for EPA protocols
Actual lot chromatograms available upon request
