PT-8000Type fully automatic blowing and capturing device

Instrument Introduction

The PT-8000 fully automatic blowing and capturing device is a new type of fully automatic blowing and capturing device developed by Beijing Zhongyi Yusheng Technology Co., Ltd. It can be loaded into 95 sample bottles at full load once and can be used with all domestic and imported GC and GCMS.

Suitable for the analysis of volatile organic compounds in liquids and solids, and can also perform derivative reaction treatment on samples. Liquid sample, taken toPurging the U-shaped tube; Low content solid samples are directly blown using a 40ml sample bottle; High content solid samples are automatically extracted and diluted with methanol before being purged.

Testeable sample types: volatile organic compounds in water, wastewater, drinking water, seawater, blood, sediment, sludge, soil, cosmetics, textiles, packaging materials, food, spices, etc.
