Gas Chromatograph Mass Spectrometer

Chromatography

Chromatography is a versatile method facilitating the isolation, characterization, and refinement of mixture constituents, supporting both qualitative and quantitative assessments. Our Gas chromatograph mass spectrometer system has a pre-filter mass analyzer and an electron multiplier to provide excellent sensitivity. Desorption for solids is carried out with a flow rate of 1 to 1.5 ml/min at a regulated temperature between 100 and 350?. The analysis is sensitive and focused, with a seven-stage temperature programming and an interface temperature of 450?. he design includes two distinct analog signal outputs, a column oven, a data acquisition system, a real-time instrument monitoring system, the acquisition of detecting signals, PC control, flexible sample injection, and M6 software. With an automatic back door opening, the oven allows for speedy heating and cooling of up to three chromatographic columns.

Frequently Asked Questions

What is Chromatography?

Chromatography is a laboratory technique used to separate, identify and analyze components in a mixture.

What is retention time in Chromatography?

It is the time taken by a component to travel through the column or stationary phase and be detected by the detector.

What is a reference standard in Chromatography?

A reference standard is a known compound used to compare retention times and ensure the accuracy and reproducibility of chromatographic results.

What is meant by elution in Chromatography?

It is the process of removing analytes from the stationary phase by passing the mobile phase through the column.

Does Temperature affect Chromatography results?

It affects the interaction between the sample components and the stationary phase.

What is the role of a detector in Chromatography?

It is used to identify and quantify the separated components upon their exit from chromatography column.
