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
1 What is Chromatography?
Chromatography is a laboratory technique used to separate, identify and analyze components in a mixture.
2 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.
3 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.
4 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.
5 Does Temperature affect Chromatography results?
It affects the interaction between the sample components and the stationary phase.
6 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.
Selection Guide for Chromatography
Chromatography is a laboratory technique used to separate, identify, and analyze components in a mixture based on their chemical properties. When selecting a chromatography system, customers should consider the sample type, target analytes, and required detection sensitivity. A Gas Chromatograph (GC) is suitable for customers analyzing volatile and semi-volatile organic compounds, commonly used in environmental labs, petrochemical industries, food safety testing, and forensic analysis. For customers needing to identify unknown compounds or detect trace levels in complex mixtures, the Gas Chromatography-Mass Spectrometer (GC-MS) is more suitable, often used in drug screening, pesticide analysis, and environmental monitoring. Meanwhile, customers dealing with water-based samples containing ions, such as anions and cations, should choose an Ion Chromatograph (IC), which is frequently applied in water quality testing, food additive analysis, and pharmaceutical research. Selecting the right system, such as GC, GC-MS, or IC, ensures customers achieve accurate, efficient, and application-specific results.
Understanding Chromatography: Purpose, Process, and Benefits
Chromatography is a powerful analytical technique used to separate, identify, and quantify components within a mixture. It plays a critical role in a wide range of scientific and industrial fields, from pharmaceuticals and environmental testing to food safety and forensic science.
It works on the principle that different compounds in a mixture will interact uniquely with a stationary phase (solid or liquid) and a mobile phase (gas or liquid), resulting in distinct separation patterns and our Chromatography contains;
High Sensitivity and Accuracy
Versatility
Automated Operation
Wide Range of Detectors
Chromatography finds wide-ranging and essential applications across multiple industries due to its ability to accurately separate and analyze complex mixtures. In the pharmaceutical industry, it is extensively used for drug development, purity analysis, stability testing, and detecting impurities in formulations to ensure safety and efficacy. Environmental testing laboratories rely on Chromatography to detect and quantify pollutants in air, water, and soil samples, supporting regulatory compliance and environmental protection. In the food and beverage sector, it is used to identify additives, preservatives, and contaminants, as well as to maintain product consistency and quality control. In biotechnology, Chromatography is crucial for protein purification, metabolite profiling, and biomolecule characterization during research and production processes. Forensic science applications include toxicology screening, drug detection, and the analysis of evidence in criminal investigations. Meanwhile, in the chemical and petrochemical industry, Chromatography helps analyze complex chemical mixtures to ensure that materials meet required specifications and quality standards. These varied applications highlight Chromatography indispensable role in modern science and industry.
