HDK-3001 Headspace Sample Injector

Product Introduction

Beijing Huilong Headspace Sampler

The HDK series multi-mode headspace sampling device is a new type of gas chromatograph sample pretreatment equipment developed and launched by Beijing Huilong Changhai Science and Trade Co., Ltd. with multiple innovations and intellectual property rights. It also broke the bottom line of cost-effectiveness for domestic headspace samplers and established a new *.

We know that in the daily analysis process of gas chromatography, the largest 10% of the error comes from the instrument being operated, while 90% comes from the quality of sample pretreatment. The advantages and disadvantages of different sample pretreatment techniques and methods vary greatly. Among them, if headspace extraction gas chromatography analysis is used, it can achieve accurate, simple, and rapid analysis of volatile compounds in almost any sample. Because headspace sampling makes it extremely easy to achieve solvent-free extraction of liquid and solid samples, it can be said to fundamentally eliminate errors and problems that may occur in sample pretreatment methods such as adsorption desorption and solvent extraction.

Features

⑴ Accurate, simple, fast, convenient, automatic, and environmentally friendly;

⑵ High sensitivity analysis of volatile components in samples;

Due to the fact that high boiling point components are not introduced into GC, analysis time can be shortened and work efficiency can be doubled;

Due to the fact that high boiling point components are not introduced into GC, it avoids contamination of the analysis system by high boiling point components, thereby reducing the daily maintenance work of the instrument and extending the life of certain key components (such as injectors, chromatography columns, detectors, etc.);
