Huilong's new 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.Also brushnew了Domestic headspace samplerThe bottom line of cost-effectiveness has established a brand new *.

We know that in the daily analysis process of gas chromatography, 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 injection (gas phase 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.);

Application areas: (1) Petrochemical industry: high polymer monomer coatings, volatile organic compounds, etc;

⑵Environmental science: volatile halogenated hydrocarbons in drinking water and organic toxic volatile compounds in industrial wastewater;

⑶Hygiene and epidemic prevention: analysis of residual disinfection and fumigation of medical supplies;

⑷Food industry: quality control of colored wine, vinegar, soy sauce, residual acetaldehyde in packaging materials, residual solvent 6 # in extracted oil;

⑸Spice essence: flavor analysis of beer and tea;

⑹Quality inspection of drugs: organic residual solvents in drugs;

⑺Forensic chemistry: determination of ethanol, ketones, and aldehydes in blood and urine;

⑻Other: such as volatile organic compounds in soil;
