Can I use HPLC grade hexane for GC?

Sometimes, but HPLC grade is tested for UV absorbance rather than GC peaks. Trace volatile impurities that are invisible to a UV detector can show up on an FID or ECD, so a GC or residue grade is the safer choice for trace work.

Why is DMSO used for headspace residual solvent testing?

DMSO has a high boiling point, dissolves most drug substances and elutes well after common residual solvents. A headspace grade is tested to show that it contributes no measurable peaks for the solvents listed in ICH Q3C.

What does a lindane equivalent mean on a COA?

Pesticide residue grade solvents report ECD-active impurities as if they were lindane, after concentrating the solvent. It gives a single figure for electron-capturing contaminants that would interfere with organochlorine residue methods.
