Temperature control is a critical part in the process of GC analysis of the sample. Because the temperature determines what type of headspace chromatography vial is selected. Aijiren headspace vial manufacturer, supply all kinds of headspace vials for sale.

Today, about 95 percent or more of HPLC systems from major manufacturers ship with autosamplers, a testament to the improved reliability and reproducibility of autosampler hardware and controls over past instruments.

In this experiment, headspace-Autosampler HS-20 instrument will be used. To suit for this headspace instrument, 20mm crimp headspace vial should be chosen. In aijiren product catalog, there are 6ml, 10ml, 20ml vials, whose size of mouth is 20mm crimp vial. A mixture of NDMA and NDEA was used to prepare calibration curves ranging from 2.5-10 ug/L. According to reagent volume, the 10ml headspace crimp vial is the suit one.

Most of the chromatography vials are made of glass, when talking about this material, we must first talk about the linear expansion coefficient, refers to the temperature changes once, the length of the glass changes.

In scientific research experiments,vials are everywhere.The chromatography vial has good chemical stability,no pollution to the contents,can be heated at high temperature, and protected from light.It has always been the main choice for pharmaceutical packaging.

2ml clear and amber screw vials for sale.Aijiren is the leading supplier of chromatography vials over 15 years.

There are so many size of chromatography vial. Standard vial sizes include 8x40mm (1mL), 15x45mm (4mL) and 12x32mm (2mL). But how to choose the suit chromatography vial in Size? The user can also select a vial with a normal (4 mm) opening or a wide (6 mm) opening, depending on the type of caps. Please read this article.

We accept our product catalogue or similar product processing commissions not published on the website, to provide you with “one-on-one” customized processing services to solve the special needs of customers' laboratories.

The sample bottles supplied by aijiren are precisely designed, applied with expertise and in accordance with strict technical specifications.

In fact, when we do liquid chromatography, the sample vial is a one-off, but the cost is too high, so now we need to use a repeated sample hplc vials

20ml headspace bottles, which are often used in Shimadzu, Spectral Physics, Varian, and other autosamplers.

The cleaning of chromatographic sample bottles is very important. According to the washing method of glass instrument, choose the cleaning method according to the pollution degree, there is no fixed mode.

In usable 6, 10, 20 milliliter size. Use a standard sample bottle to ensure adequate top space. This must be done in a standard scale and of course must be done without over-diluting the used sample.

This article mainly introduce the types of lcgc vials.

We have introduced five cleaning methods of chromatographic sample bottles, I hope you can pay attention to the chromatographic sample bottles cleaning.
