What is GCMS (Gas Chromatograph and Mass Spectrometry)?
GCMS (Gas Chromatograph and Mass Spectrometry) is widely used in the separation and identification of complex components, which has a high resolution of GC and the high sensitivity of mass spectrometry. GCMS is mainly composed of the following parts: chromatographic, gas interface, mass spectrometer part (ion source, mass analyzer, detector), and data processing system. Gas-mass spectrometry (GCMS) is…
Learn About Lab Freeze Dryer in 8 minutes
A freeze dryer is a technical method that pre-freezes water-containing items, and then sublimates its moisture in a vacuum state to obtain dry items. The freeze-dried articles are easy to be stored for a long time and can be restored to the state before freeze-drying and maintain the original biochemical properties after adding water. Vacuum freeze-drying technology…
Troubleshooting of High Performance Liquid Chromatography (HPLC)
There are many test instruments used in the laboratory, and high-performance liquid chromatography (HPLC) is one of them. The instrument is based on classical chromatography, citing the theory of gas chromatography, and technically it changes the traditional mobile phase to high-pressure delivery. This article will introduce the principle and application, characteristics, failure causes, and treatment…
Is The X-Ray Fluorescence Reliable For Gold Detection?
The use of portable X-ray fluorescence across the industry has been remarkable over the past few years. Originally born in the alloy and scrap metal detection industry, the technology was later determined to be effective in environmental field monitoring, particularly contaminated land and remediation work. It can be said that the use of portable XRF in soil science…
What Is an Autoclave? What’s It for?
High-pressure steam sterilization is a commonly used sterilization method in biological experiments. Whereas, an autoclave is an autoclave device used in a laboratory. According to the size of the capacity, the autoclave can be divided into three types: portable, vertical, and horizontal. An autoclave is widely used in medical schools, medical and health, food chemical, biological research,…
4 Reasons for Spectrophotometer Measurement Error
A spectrophotometer is an instrument that takes advantage of the selective absorption of light by substances and uses purer monochromatic light as incident light to measure the absorption of light by substances, to perform qualitative or quantitative analysis of substances. Frequently used spectrophotometers include digital spectrophotometer, UV spectrophotometer, fluorescence spectrophotometer, etc. Measurement errors often occur during use. How…
Is Ion Chromatography (IG) the Best Chromatograph?
Ion Chromatography is a type of high-performance liquid chromatography (HPLC), which is a liquid chromatography method for analyzing anions and cations. Like HPLCIC exploits the inherent affinity of ion pairs for the “eluent” (usually buffered water) and the “stationary phase” (porous solid support with charged functional groups). In a narrow sense, ion chromatography is a chromatographic method…
The Experiment Must See! How to Use the Centrifuge Correctly?
The Centrifuge is a very commonly used separation instrument in laboratories. It is widely used in the separation of experimental materials in biomedicine, petrochemical, agriculture, food hygiene, and other fields. Since the centrifuge was invented, it has undergone low-speed, adjusted, and over-speed changes. Its progress is mainly reflected in the two aspects of centrifugal equipment and centrifugal technology,…
You Need To Know These Things About Spectrophotometer!
A spectrophotometer, also known as a spectrometer, is a scientific instrument that decomposes complex light into spectral lines. The measurement range of the spectrometer generally includes the visible light region with a wavelength range of 380 to 780 nm and the ultraviolet light region with a wavelength range of 200 to 380 nm. Different light sources…
What is an Alloy Analyzer?
Alloy analyzer was born based on X-ray theory. It is mainly used for field determination of elemental composition in metal materials in military, aerospace, steel, petrochemical, electric power, pharmaceutical, and other fields. How Does the Alloy Analyzer Work? The alloy analyzer is a kind of XRF spectroscopy analysis technology, which can be used to confirm the…
