Grade guide
GC Grade chemicals
Solvents tested for gas chromatography: high GC purity, low non-volatile residue and minimal peaks that interfere with FID, ECD or MS detection.

FAQs
What is pesticide residue grade?
A GC solvent grade tested after concentration, typically with an electron capture detector, to show that it adds no interfering peaks in trace pesticide analysis.
Which solvent is used for headspace residual solvent testing?
High-boiling solvents such as DMSO, DMF, DMAc or water are common diluents. Headspace grade versions are tested for low levels of the volatile solvents being measured.
Does GC grade solvent need to be filtered?
Particles matter less than in HPLC, but solvents should still be clean. The key GC parameters are chromatographic purity and low non-volatile residue.
