Chromatography And Spectrometry Instruments
What are the basic instrumentations of chromatography and spectrometry?
Chromatography encompasses a broad spectrum of techniques and instrumentation tailored to diverse analytical applications. At SCION, we offer a comprehensive range of state-of-the-art chromatography solutions to meet varied research and testing needs. Our portfolio includes gas chromatography instruments like the SCION 8500 and SCION 8300, mass spectrometry detectors such as the SCION 8700 and SCION 8900, and the versatile LC6000 HPLC system. Each of these instruments are designed to deliver unparalleled analytical performance, reliability, and efficiency.
Gas Chromatography
Gas chromatography (GC) is a highly effective technique for separating and analyzing volatile compounds in mixtures. SCION provides advanced gas chromatography instruments designed for high performance and flexibility.
Our Gas chromatography instruments can be traced back to our heritage of Chrompack and Varian, which were acquired by the Techcomp Group in 2014. Over the years, significant technological advancements have enhanced the performance, efficiency, and user-friendliness of our gas chromatography instruments.
We transitioned from the Varian 456 and 450 series to the next-generation SCION 8500 and 8300 models.
SCION 8500 GC: The SCION 8500 is our most versatile gas chromatography platform, offering superior performance for a wide range of applications. It supports up to four data outputs, an extensive selection of detectors and inlets and nine electronic flow control (EFC) channels. The SCION 8500 GC is an ideal solution for complex analytical challenges. We also provide pre-configured solutions for standard methods, as well as customizable solutions for specialized needs.
SCION 8300 GC: The SCION 8300 GC is the ideal solution for laboratories with limited space, offering exceptional performance in a compact, space-efficient design. Measuring just 32 cm (12.6 inches) in width, this streamlined instrument maximizes functionality without compromising on precision or productivity. Despite its small footprint, the 8300 GC supports up to two detectors, including a Mass Spectrometer, making it a versatile and powerful choice for space-conscious labs.
HPLC Chromatography Instrument
HPLC Instruments are essential for separating, identifying, and quantifying volatile and non-volatile compounds in complex chemical mixtures. Widely employed in industries like pharmaceuticals, medical research, food safety, and drug testing, HPLC is a cornerstone of analytical chemistry.
The SCION LC6000 is engineered for precision, reliability, and speed, offering consistent performance to ensure confidence in results. Designed to maximize uptime and minimize operational costs, the LC6000 features a range of automation options to streamline workflows and enhance laboratory efficiency. At SCION our team of experts will collaborate with customers to tailor configurations that meet their unique requirements, delivering optimized solutions for every.
Mass Spectrometry
Mass Spectrometry instruments offer a powerful analytical technique that pairs with gas chromatography (GC) to analyse complex chemical mixtures. In this process, the mass spectrometer instrument acts as a detector, identifying and quantifying vaporized compounds separated by GC. While GC provides data on retention time and peak intensity, MS adds vital mass data, enabling deeper insights into the structural and chemical properties of molecules.
SCION Mass Spectrometry Models
SCION 8700 Single Quadrupole (SQ): Designed for seamless integration with SCION GC systems, the 8700 delivers reliable and precise single-quadrupole analysis for complex chemical mixtures.
SCION 8900 Triple Quadrupole (TQ): For advanced applications, the 8900 offers triple-quadrupole functionality, enabling greater sensitivity and specificity for demanding analytical challenges.
At SCION, our mission is to deliver cutting-edge chromatography and mass spectrometry instruments that meet the evolving needs of modern laboratories. Whether your focus is routine analysis or advanced research, our solutions are engineered to deliver exceptional performance, reliability, and value.
What does gas chromatography tell you?
The process begins by introducing a sample into a chromatography instrument, where it is vaporized and carried through a column by an inert gas, known as the mobile phase. As the sample moves through the column, different components of the mixture interact with the stationary phase (the material coating the column) to varying degrees, leading to their separation based on properties such as boiling point, polarity, and molecular weight.
The results of this separation are displayed in a chromatogram, a graphical representation where each peak corresponds to a different component of the mixture. The position of a peak on the horizontal axis indicates the retention time, which is the time taken for a specific compound to travel through the column and emerge at the detector. The height or area of each peak is proportional to the concentration of that component in the sample, allowing for quantification.
In addition to providing information about the chemical composition and relative amounts of substances in a sample, GC can also be coupled with other analytical techniques, such as mass spectrometry (MS), for enhanced analysis. This combination allows for detailed structural and chemical characterization of the separated compounds, offering deeper insights into the sample’s properties and potential applications.

What is the difference between paper and column chromatography?
Paper chromatography and column chromatography are both analytical techniques used to separate and analyse mixtures based on their differing affinities for a stationary phase and a mobile phase.
In paper chromatography, a sheet of paper—typically made of cellulose—serves as the stationary phase, while a solvent acts as the mobile phase, moving through the paper. The separation of components in paper chromatography relies on their differences in polarity and solubility, allowing for the distinct visualization of separated substances.
In contrast, column chromatography employs a vertical column filled with a solid stationary phase, such as silica gel. A liquid solvent is passed through the column, facilitating the separation of compounds. The effectiveness of column chromatography lies in its ability to separate substances based on various interactions with the stationary phase. By adjusting the composition of the mobile phase, researchers can enhance the separation of components, making this method particularly versatile for complex mixtures.
Both techniques are valuable for analysing chemical mixtures and are widely used in various fields, including biochemistry, environmental science, and pharmaceuticals, enabling scientists to isolate and identify individual compounds within a sample.
