Residual Solvent Analysis
Residual organic solvents in APIs, intermediates, formulations and products — by Headspace GC against product and ICH-class limits.
Gas-chromatography analysis of solvents and volatile organics — residual solvents, VOCs, BTEX and solvent purity — determined by GC-FID, GC-MS and Headspace GC for pharma, chemical, dye and paint industries across Gujarat.
Aura Environmental Services Pvt. Ltd. runs gas chromatography (GC) in its NABL-accredited laboratory in Odhav, Ahmedabad. We separate, identify and quantify volatile and semi-volatile organic compounds — residual solvents in products and intermediates, VOCs in ambient and work-zone air, BTEX in water and effluent, and the purity of recovered solvents — using GC-FID, GC-MS and Headspace GC to ISO/IEC 17025 methods for product quality, workplace safety and GPCB/CPCB compliance.
