How To Improve Your Gas Chromatography Analysis

What is Gas Chromatography? Gas Chromatography is a commonly used type of Chromatography in analytical chemistry. This is a very effective practice when you need to separate substances of analytical interest. Gas Chromatography uses chromatographic techniques when applying a gas as the mobile phase and a solid or liquid as stationary phases. The principle of Gas Chromatography involves a controlled carrier gas stream that passes through an injector, column, and detector. Then a sample gas is injected for a short period of time, creating a gas sample plug. This is then separated into different gas components across the column. They

A Low Temperature, Safe, and Effective Way to Sterilize Reusable Medical Devices and Equipment

Steam is by far the most common method of medical sterilization used in the U.S today. High temperatures produced by steam are not compatible with all materials and it has other disadvantages. The most prominent low temperature sterilization method currently used is ethylene oxide. EO is a relatively dangerous and toxic material. Vaporized Hydrogen Peroxide: H2O2 has many advantages including low toxicity, low temperature, and relatively good material compatibility. There are several methods in use today this article discusses HPV or hydrogen peroxide vaporization. Using A Controlled Evaporation Mixer To Deliver The Vaporized Hydrogen Peroxide A Controlled Evaporative Mixer or

What is a Controlled Evaporation Mixer (CEM)?

Liquid Delivery System with a Controlled Evaporation Mixer We have many customers that have applications where two components must be mixed. Traditionally, bubbler systems or Vapor Source Controllers have been used when dealing with vapor. These devices have their shortcomings, for example they have been proven to not be able to handle large quantities of liquid with a low vapor pressure. Furthermore, they can’t provide vapor from a mixture of liquids with different vapor pressures. Our partners at Bronkhorst have worked hard to develop a system that has Mass Flow Control of Vapors. This system is our Controlled Evaporation Mixer

6 old ways to generate vapor versus 1 new way!

Generating vapor is now easier, quicker and more accurate. Generating vapor is a perfect example of how technology development in one are can benefit multiple industries. By combing the accuracy and digital performance of modern mass flow metering and control technology, alongside temperature control you can control the properties of vapor as never before. Vapor production has always been a necessary, but complex and expensive process. There have been multiple methods employed to achieve the dispersion of liquid into a gas phase. The variety of methods used is a reflection of the bespoke approach taken by many to compensate for

CEM: Liquid Delivery System with Vapor Control

Liquid Delivery System with Vapor Control Introduction: In a number of processes two or more components must be mixed together. In instances where it comprises a vapor of a liquid in a carrier gas, traditional Bubbler Systems and the more recent Vapor Source Controllers have been used. These devices, however, can often not handle sufficient quantities of liquid with a low vapor pressure, or perform in an imperfect way. Moreover, they cannot instantaneously provide vapor of a mixture of liquids with different vapor pressures. Bronkhorst has therefore developed a unique patented system to realize Mass Flow Control of Vapors with
