Selection Guide of Electric Rotary Valve in Precision Fluidics

Selection Guide of Electric Rotary Valve in Precision Fluidics

A multi-channel electric rotary valve is a type of valve that is used to control the flow of fluids in precision fluidic systems. It is typically used in applications where precise control of fluid flow is required, such as in the manufacturing of semiconductors or the analysis of biological samples.  The basic principle of a rotary valve is that it uses a rotor with multiple channels or openings to control the flow of fluid through a system. The rotor is mounted on a shaft and can be rotated to align the channels with inlet and outlet ports in the valve body. When the channels are aligned with the inlet and outlet ports, fluid can flow through the valve. When the channels are not aligned with the inlet and outlet ports, the flow of fluid is blocked.

The Basics of Corona Discharger Treatment and Equipment Selection Guide

The Basics of Corona Discharger Treatment and Equipment Selection Guide

Corona dischargers are a type of electrical discharge device that is used to remove contaminants and impurities from various materials, such as gases, liquids, and plastics. This is achieved by creating an electrical discharge or plasma field around the material, which ionizes the contaminants and causes them to become charged. The charged particles can then be attracted to and neutralized by a collector plate or other type of electrode.

Glove Box Selection Guidelines

Glove Box Selection Guidelines

A glove box is a sealed container that is designed to allow operators to perform tasks in a controlled environment without direct contact with the materials inside. Glove boxes are commonly used in a variety of applications, including handling hazardous materials, conducting experiments in a sterile environment, and working with sensitive equipment.   When selecting a glove box, there are several factors to consider. These include the size and shape of the box, the materials used in its construction, the type of gloves and other protective equipment included with the box, and the specific features and accessories that are available.   

Application of FLUORINATED oil FLUO-OIL 135 Used in Droplet-Based Microfluidics

Application of FLUORINATED oil FLUO-OIL 135 Used in Droplet-Based Microfluidics

Fluorinated oils have received increasing interest over the last few years, as applications in the field of microfluidics have largely expanded. Especially, droplet-based microfluidic platforms have successfully been developed for a wide range of applications such as macromolecular engineering, drug screening, digital PCR or cell encapsulation and sorting, to name a few. Droplets are also widely used as microreactors for chemical or biological reactions as they allow running thousands of experiments in parallel while minimizing costs and volumes in a time-effective manner. 

For all these applications, the compartmentalization into droplets requires a fluid that is immiscible with water and a surfactant to prevent droplets from merging. By far, the preferred fluids for such applications are fluorocarbon oils. They are inodorous, transparent, and they exhibit great retention of reagents in droplets since most organic compounds are insoluble in fluorinated oils.

Gas Chromatography(GC)  Column Selection Guide

Gas Chromatography(GC) Column Selection Guide

Gas chromatography(GC) is a simple, fast, efficient and sensitive modern separation and analysis technology, which is widely used in scientific research and inspection departments such as environment, medicine, chemistry and chemical industry, and it is also an indispensable detection method for the determination of pesticide residues. Gas chromatograph has the advantages of fast analysis speed, high separation efficiency, high sensitivity, high selectivity, etc. However, due to the complexity of the sample matrix, operator error, and the instrument itself during the analysis process, the gas chromatograph will have various problems, which will affect the results of chromatographic analysis.  Thus, it is critical to have in-depth understanding of the common solutions for gas phase analysis.

Applications of Ghost-Buster II in Removing “Ghost peaks” and Baseline Drift in HPLC analysis

Applications of Ghost-Buster II in Removing “Ghost peaks” and Baseline Drift in HPLC analysis

During HPLC analysis, especially in gradient elution or after long time system usage, some unexpected peaks called "Ghost Peaks" may appear in the chromatogram, particularly when UV-vis or PDA detector are used.  These Ghost peaks can interfere the data interpretation and analysis.  Welch Materials original Ghost-Buster Column I can capture ghost peaks, but sometimes it comes with baseline fluctuation. This can affect the integration of some peaks.  Ghost-Buster Column II is a new product upgraded from the version I of Ghost-Buster Column.  It can remove impurities of low polarity and prevent interferences from different kinds of ghost peaks.  It can also resolve the baseline drift caused by the excessive initial proportion of aqueous phase in the gradient program.
