The extracted protein samples are then quantified to ensure the use of the same amount of protein in the experiment.Protein SeparationProteins are separated into different bands or peaks using gel electrophoresis (such as SDS-PAGE), or liquid chromatography (like HPLC).Mass Spectrometry AnalysisMass spectrometry techniques are used to identify and quantify the separated proteins, ...
Gas Chromatography (GC) method validation is a cornerstone of analytical chemistry, ensuring that quantitative analysis methods are reliable and accurate. As scientists, we know that precision is non-negotiable, especially when dealing with critical applications in industries such as pharmaceuticals, environmental monitoring, and food safety. High accuracy standards are not just a recommendation; ...
A Chromatography Data System (CDS) plays a pivotal role in instrument control, data processing, report generation and data archiving. ...

They are simple and easy to use with a control interface that allows for the setting of the ambient temperature +7℃ to +60℃ and preset at the factory to 37℃ and 56℃.Chromatography – ScionSCION Instruments is a leading supplier of Chromatography instrumentation and solutions. It is committed to continuing its 50+ year legacy of product innovation, providing true ...
Abstract Calculated profile mode mass spectrometry (MS) data are fitted to lineshape-calibrated liquid chromatography LC/MS data using a Multiple Linear Regression (MLR) model to quantitate the relative concentrations of stable or radiolabeled compound mixtures. This alternative approach significantly improves the precision and accuracy over ...
Charged Aerosol Detection (CAD) is a detector with high sensitivity and good repeatability used to detect most non-volatile and semi-volatile organic compounds. Its uses cover a wide range of applications, including analysis of pharmaceutical ingredients, analysis of natural products, and analysis of sugars, proteins and surfactants. Nitrogen gas plays multiple roles of atomization, drying and ...

In the last Empower Tip of the Week for Empower Chromatography Data Software (CDS), we explored how to compare calibration curves. ...
Because it opens a new door to mass spectral data. Guillarme – a chromatography specialist – explains why simple but robust mass detection has found an important role in method development in his world: pharmaceutical analysis. ...
My time at AstraZeneca allowed me to get “hands on” with a number of chromatography and mass spectrometry platforms, and provided me with an acute awareness of the need for reliable data and robust instrumentation – something that was reinforced when I joined Reach Separations. ...
Tip# 2: Interactive Help (Show Me) The Empower QuickStart interface in Empower Chromatography Data Software (CDS) contains an interactive help feature called Show Me. ...
Tip #1: An Overview The Empower QuickStart Interface is great for new or infrequent Empower users of Empower Chromatography Data Software. When you login to Empower, you select a project to work in and a chromatographic system (HPLC, GC) to use for data acquisition (Figure 1). ...
To further examine this hypothesis, urine samples were collected from patients diagnosed with either bladder cancer or a non-cancerous urological disease/infection, and from healthy volunteers, from which the volatile metabolomes were analysed using gas chromatography mass spectrometry. The acquired data were subjected to a specifically designed pattern ...
Then you need to consider the chromatography data software (CDS) that you are using for your separation experiment. ...
The thought of transferring established high performance liquid chromatography (HPLC) methods onto a another vendor’s LC, or a new platform like UHPLC/UPLC, may cause a bit of anxiety for those that may be unaware of how easy it can be. ...
The company selected Thermo Scientific LIMS to improve efficiencies and product integrity and Thermo Fisher Scientific*s Atlas chromatography data system (CDS) to improve productivity in the laboratory. ...
Acquisition and Processing of Chromatography Data In former times an analytical chemist spent most of the time with the analysis itself. ...
The use of auto-carrier, frontal elution chromatography in conjunction with a process UV spectrometer allows for rapid online analysis of trace components even in complex streams containing interfering species. A unique implementation of this methodology is described and a thorough explanation of auto-carrier frontal elution chromatography is provided, along with ...
