Obtaining precise results in X-ray fluorescence (XRF) analysis requires thorough and proper sample preparation. For liquid samples, meticulous preparation ensures high accuracy and reproducibility of measurement outcomes. This article covers essential aspects of liquid sample preparation and handling procedures for XRF ...
Seawaters pose analytical challenges due to the high salt content of the sample & low environmental concentrations of the target analytes. P S Analytical systems are not affected by these issues and are ideally suited to this ...
Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is a powerful analytical technique for the study of powdered and rough surface materials. It is widely employed for quality control, materials characterisation and catalytic studies in both research and industrial settings. However, optimal sample preparation and instrument setup are crucial to obtain the most reliable results ...

Combined with non-dispersive infrared (NDIR) technology and long-lifetime electrochemical sensor technology (EDC), Gasboard-9801 delivers exceptional accuracy in measuring critical emissions parameters, including THC&CH4, NO, NO2, CO, CO2 and O2 concentrations for both diluted and raw exhaust gases. With its wide measurement range, Gasboard-9801 excels in all laboratory ...
Formation of Bubbles in the Sample PoolIf the operation is improper when loading the sample, bubbles may easily form in the sample pool, causing increased pressure.2. High Viscosity of the SampleHigh viscosity samples may cause increased pressure during flow.3. Blockage of the Sample PoolContaminants, sediments, ...
Preparation of Protein Standard SolutionPrepare a series of standard solutions using a protein of known concentration (such as bovine serum albumin, BSA) to draw a standard curve.3. Sample PreparationDilute the protein sample to the expected testing range.Analysis Workflow1. ...
It is currently widely used in determining the secondary structure of proteins, and is a fast, simple, and relatively accurate method for studying the conformation of proteins in dilute solutions.Analysis Workflow1. Sample PreparationHigh concentration protein solution is obtained from the sample by purification techniques such as chromatography ...
In this study, fast methods (adenosine triphosphate (ATP), flow cytometry, enzyme activity and qPCR) were compared as an alternative for HPC22. Using dilution series and field samples, ATP (ATPtotal-lab and ATPcell-mob) and enzymatic activity (ALP-2) methods proved to be the more reliable and sensitive than flow cytometry and qPCR methods for detecting ...
To obtain accurate and reliable results, two fundamental procedures are frequently required that afford utmost precision: calibration of the analytical system and dilution of highly concentrated samples. When using ion chromatography, fully automated solutions exist to reduce this manual lab work and facilitate efficiency. Sample preparation ...

Introduction Extending lubricant condition monitoring programs to include grease analysis Onsite oil analysis is an effective tool to quickly analyze samples and optimize maintenance activities. As part of a comprehensive condition based maintenance program (CBM), oil analysis proves to be an effective tool to compliment other diagnostic technologies like vibration analysis, infrared ...
Principle of ITC The ITC instrument contains a reference pool and a sample pool, in which a dilute solution is added to the reference pool as a control, separated from each other by a thermal insulation device. ...
This process is done through sample preparation. Alongside the removal of any interferences, sample preparation is also completed to dilute or concentrate samples. Sample preparation techniques such as Liquid-Liquid Extract, Solid Phase Extraction and sample filtering, ensure clean ...
Weigh the sample and add a certain amount of aqua regia until the sample is completely dissolved. ...
When nitrite is used as a corrosion inhibitor, it becomes crucial to maintain its concentration above a certain level to prevent localized corrosion from happening.Monitoring of nitrite is most commonly done by grab sample testing. The testing is typically done using kits that rely on drop count titration methods which may require a third-party service company to visit the ...
Electrode care is required consistently to ensure an accurate reading for any application, but the frequency of cleaning varies dramatically. The best way to determine a cleaning schedule is by calibrating on first use then checking frequently with a standard. Once the measurement is out of acceptable range, then record how long that took and recalibrate. Use the recorded time as a ...
There is always something to do in a laboratory, whether it is dispensing, dilution, sample transfers, or standard preparation. On top of this, if you work in a lab, you probably have deadlines to meet, reports to file, publications to write, and the crushing pressure to produce more results. ...
All the reagent handling for Microwave digestions before and after the digestion can be handled in Automated sample Handling system, Vulcan. You can now have fast digestions without concerns for reagent handling and dilutions and save a lot of time for analyzing and understanding the results. Automated Liquid Transfer and dilution The QPrep ...
One of the main reasons for this is the hugely simpler sample preparation. ICP-MS instruments most commonly analyse samples in a dilute acid matrix, and for some sample types, the sample preparation is simply a case of diluting the sample to a suitable concentration to enable ...
One of the most frequent mistakes is to collect the sample in a bottle with sodium thiosulfate for culture analysis and without sodium thiosulfate for ATP analysis. ...
Venacontra delivered Diluting Aerosol Sampler (DAS) during the year 2012 for the HICE – The Helmholtz Virtual Institute of Complex Molecular Systems in Environmental Health consortium. DAS has been succesfully used in various HICE measurement campaigns including the following combustion sources: marine applications with heavy fuel oil and marine gas oil vehicle emissions small ...
