The Role of Autosamplers in Chromatography

Chromatography refers to the scientific process that consists of several lab based techniques used to separate a mixture. This mixture is firstly dissolved in gas or fluid and then carried to some other material to create stationary phase. Facilitating the speed of travel, the process helps to separate the compounds present within the mixture. It might be used as purifying process for feature analyte proportions of mixture. The idea is to make at least one part of the mixture to be stationary or immobile and the other to be mobile.

Gas Chromatography refers to the process of analysis of compounds using gas chromatograph- a machine that perform the analysis of compounds after being separated from the sample and has been vaporized. A column inlet, also known as injector helps to remove the compounds from the sample.

An autosampler is equipment that is used in the process of chromatography to ensure the accuracy during testing or inserting the portions. The instrument inserts the sample parts into the inlets of apparatus during the test with an increased efficiency and results. Now the autosamplers have become a common method of completing different types of chromatography techniques.

Instruments involved with the separation lab techniques

Gas chromatography is one of the common process for sampling the analytical instruments. It is usually used to test compounds that are capable of vaporizing without decomposing. GC can help the laboratories test and separate the mixture and its substances, identify the compounds present and create pure version of the liquid. Helim or any other nonreactive gases act as the carrier in such processes during mobile phase whereas a liquid is present inside the column for the stationary phase.

 

The various gas compounds react with the stationary phase elements causing the compounds to elute the different retention times. A liquid volume is inserted into the column either automatically or manually with special equipments. Motions are created by molecule absorption which determines the molecule progression rate. Progression is affected by absorption strength, molecule types and stationary phase material. 

An autosampler is a kind of tool that is used to achieve insertion into the columns through automatic methods. The insertion point if referred to as an inlet and comes in the form of split less, split, on column, purge and trap, PTV injectors or gas switching value. Manual insertion leaves much room for errors that can compromise and affect the test results and are also time consuming. 

Samplers are classified depending upon the sample capacity, type of technology, analytical purposes or other. They are also used for a variety of separation process that includes the measurement of volatile organic compounds. Automatic sampling has greatly improved the process and gas chromatography process as well as other separation processes.

How to Use Autosampler?

An Autosampler is an instrument which can be used for different laboratory applications, specifically for Gas Liquid Chromatography. It is, as the name implies, used to automatically introduce the sample into the inlets of the apparatus employed in the test. While it is possible to insert the samples manually into the instrument, it is no more a common practice as the auto samplers are more efficient and precise method to accomplish results.

Autosamplers can be classified by their capacity such as auto injectors that are capable of running multiple samples in one go. Robotic instruments also offer another classification of these autosamplers with the rotating robots that are being used widely. In the gas liquid chromatography process, the injector or the column inlet provide the introduction of the samples as a continuous flow of the carrier gases. Common inlet types include the split injectors, splitless injectors, on columns inlets, gas source inlet called as Gas switching valves and PTV injectors.  Other systems might include the Solid Phase micro extractions, Purge and Trap Systems and others. In split and splitless injector, the sample is introduced using the syringe to heated chamber.

With on column inlet, the sample is then introduced in its entirety sans the use of heat. The PTV injectors then introduce the sample at a very controlled temperature through a heater liner. In the gas source inlet method, the sample is injected into the gas stream right from the collection bottle, a methods that is used to introduce without any interruption to the flow of the gas.

The purge and trap autosampler system involves the bubbling of an inert gas through purging insoluble volatile compound and the aqueous samples using the matrix. These compounds are later on trapped in an absorbent column which on heating volatizes to the carrier stream.

The type of the autosampling system used largely depends on the application. In Gas Chromatography alone, there are 2 distinct types of columns being used based upon the type of autosampler being used. There are packaged columns that are usually made up of stainless steel and glass and contain highly granular, inert and solid material coated with some solid or liquid stationary phase.

The other type is Capillary Columns. These columns feature a small internal diameter that is being coated inside with the phase. Other types of capillary columns are made up of semi solid construction which allows greater flexibility. This allows a long column be tight wounded into coil which takes up very less room.

While it is usually gas liquid chromatography that often comes to the mind when are discussing autosampler types, there are samplers that are being used in different applications from the geological surveys to life sciences, Pharma industry to water quality testing and nearly every other application in the materials and life sciences as well as quality control testing of all types. These instruments have allowed the labs to handle minute and high samples while increasing efficiency and production. 

Benefits of Gas Chromatography

Gas Chromatography is a very similar technique to that of column photography. The only difference is that in this process, gas is used a mobile phase as compared to liquid. GasChromatograph is now widely used technique and element that helps in separation of gaseous and volatile components that are difficult to analyze and separate other ways. Gas chromatography has wide applications for separating the volatile sample.

Portable GCs & Hand Held Analyzer Features and Benefits

Portable GCs or Portable Chromatographs

A gas chromatograph helps to separate the gaseous volatile compounds being varied by inert gases like Nitrogen, Argon, Hydrogen, Helium or Hydrogen across a solid stationary phase. The components in a gas chromatograph include a GC Capillary Column, Capillary Column, column oven, detector, a computer for data acquisition and analysis. The combination of pumps and electronic sensors maintain a constant or a variable mobile phase flow rate. GC instruments typically have a maximum temperature of 350C to 450C.
