- Description
Gas chromatograph with automatic headspace sampler and cryogenic grinder for measuring free acetaldehyde in PET preforms and bottle resin. Used by beverage and water bottle suppliers to control taste-affecting AA levels in ppm.
Specification
Ground preform sample is heated in a sealed vial, and the headspace gas is injected into a capillary column with flame ionisation detection. Acetaldehyde is quantified against calibrated standards in ppm. It supports routine release of low-AA preform grades.
Features
- Automatic headspace sampler for 12 vials
- FID detector for ppm level sensitivity
- Programmable column oven up to 350 deg C
- Cryogenic freezer mill for sample grinding
- Chromatography software with calibration curve
