What are Characteristics of Chromatography?

The chromatography technical refers to a kind of method for separating components of a mixture by utilizing the difference in performance of each component in two phases. It is considered as an essential way to separate and purify organic or inorganic substances. It is pretty effective for the separation of complicated mixtures, isomers or homologs […]

How to Troubleshoot High Performance Liquid Chromatography?

High performance liquid chromatography plays an important role in pharmaceutical, chemical, biological, genetic engineering and other fields, with the advantages of high separation efficiency, good selectivity, sensitiveness, quickness and less sample. However, some troubles may inevitably appear during the operation, which can influence its working performance. It’s necessary to rapidly and accurately solve these troubles […]

What are Types of Chromatography?

Chromatography, known as chromatography analysis as well, is a type of separation and analysis method. The common chromatography methods primarily consists of column chromatography (CC), thin layer chromatography (TLC), high-performance liquid chromatography (HPLC), gas chromatography (GC) and supercritical fluid chromatography (SFC).   1. Column Chromatography (CC) As the original chromatography, it injects the stationary phase into […]

How to Use Preparative Chromatography?

The preparative chromatography is a kind of modular purification device with powerful functions. It improves the purification process in Chinese herbal medicine, chemical synthesis, and drug separation of biological protein, allowing the gradient elution of four different solvents. It is necessary to know how to use preparative chromatography correctly and properly for better use. 1. […]

What is Liquid Chromatography Used for?

Liquid chromatography can further fall into Liquid-Liquid Chromatography and Liquid-Solid Chromatography based on the condition of stationary phase. It is mainly composed of high pressure infusion pump, sampling system, temperature control system, chromatography column, detector, signal recording system and other parts. With the continuous improvement of liquid chromatography, it can be used in more fields. […]

What is Liquid Chromatography and How does It Work?

What are the 4 Types of Chromatography? Chromatography, also known as chromatography analysis, is a kind of separation and analysis method, which is widely used in analytical chemistry, organic chemistry and biochemistry. There are four main types of chromatography, which are Liquid Chromatography, Gas Chromatography, Thin-Layer Chromatography and Paper Chromatography respectively. We will mainly talk […]

What are Advantages of Preparative Chromatography?

The preparative chromatography is a kind of modular purification device with powerful functions. It improves the purification process in Chinese herbal medicine, chemical synthesis, and drug separation of biological protein, allowing the gradient elution of four different solvents. Two wavelengths can simultaneously monitor the process on line. The software conforms to the regulations of CFDA […]
