Fully automatic solid-phase microextraction

Fully automatic solid-phase microextraction is a new type of sample pretreatment and injection technology, based on the combination of headspace technology and solid-phase microextraction technology. The software can switch between headspace injection or solid-phase microextraction injection with just one click, meeting different injection requirements. It can be applied to the analysis of target compounds in various environmental samples such as water, soil, and air, and can also be used for residue analysis in fields such as food and medicine.

1、 Product Introduction:

　　Fully automatic solid-phase microextractionIt is a new type of sample pretreatment injection technology, based on the combination of headspace technology and solid-phase microextraction technology. The software can switch between headspace injection or solid-phase microextraction injection with just one click, meeting different injection requirements. It can be applied to the analysis of target compounds in various environmental samples such as water, soil, and air, and can also be used for residue analysis in fields such as food and medicine. This method has the advantages of easy operation, high sensitivity, and good selectivity, and has become an important analytical method in the fields of environmental and food testing.

2、 Application:

This system is applicable for the analysis of geosmin, 2-methylisoborneol, carbon tetrachloride, benzene derivatives, etc. in the "GB/T 5750.8-2023 Standard Test Methods for Drinking Water"; Analysis of flavor compounds in food and alcohol.

3、 Advantages:

With independent solid-phase microextraction injection system and headspace injection system, combined with GC's automatic sampler, one chromatographic injection port can achieve solid-phase microextraction injection, headspace injection, and liquid injection, truly realizing the three functions of one chromatographic injection port, improving efficiency, and avoiding the cumbersome replacement dilemma of similar traditional injection systems.

4、 Parameters:

1. Needle change: When changing the injection mode, the injection needle can be automatically switched.

2. Automatic sample pretreatment: It can achieve automatic extraction, automatic triggering of GC or GC-MS injection, automatic activation, and analysis operations.

3. Sample bottle: with a capacity of 20mL.

4. Sample size: 54 digits.
