Undoubtedly, the most extensively used standard test method for assessing the performance of XRF instruments (and other analytical techniques) in cement analysis is ASTM C - 114, titled "Standard Test Method for Chemical Analysis of Hydraulic Cement." ...
Solid Samples The main drawbacks of solid samples are that, generally speaking, various addition methods cannot be utilized: such as the standard addition (or dilution) method, the low (or high) absorption dilution method, and the internal standard method. ...
Shotgun Protein Identification, also known as discovery-based proteomics, is a powerful analytical technique that allows for the comprehensive identification and quantification of proteins within complex biological samples. This high-throughput approach involves the digestion of proteins into peptides, followed by their separation using liquid chromatography and subsequent ...
PLFA analysis has become a popular method for characterizing microbial communities in soil, water, and other environmental samples. ...
Sample Processing The samples are prepared for conservation wherein methods differ per sample type. ...
· Label-free Proteomics of Exosomes In the proteomic analysis of exosome samples, label-free is the most commonly used technique. Creative Biolabs provides label-free proteomics for the discovery of biomarkers, which has overcome the limitation of labeling and quantitative technology in the number of samples and can be implemented in a short experiment ...
Environmental Protection Agency Method 557 (EPA 557). The new Thermo Scientific Disinfection By-Products (HAAs) Application Workflow uses the Thermo Scientific Dionex ICS-6000 HPIC system and a Thermo Scientific Dionex IonPac AS31 column coupled with triple quadrupole mass spectrometry, to deliver a fast, sensitive and simple method, that has been developed for ...
John’s background includes over 20 years with Johnson & Johnson during which he spent the majority of his time working with robotics, automating previously manual processes and developing sample preparation and assay methods utilizing a variety of liquid handlers, among many other activities. ...
The standardized workflows consist of automated sample preparation for untargeted and targeted methods in combination with the Thermo Scientific Orbitrap Exploris 480 and Thermo Scientific Orbitrap Exploris 240 mass spectrometers. ...
Any developer of a sample-to-answer device knows that getting sample prep working on-cartridge is a major source of risk. It makes matters worse that issues with sample prep usually arise late in the development process. Sample prep is often responsible when product development runs over time and over budget. Sample prep surprises often occur when developers transition a working benchtop ...
Porting a benchtop method to a cartridge can be a challenge, but changing a sample prep method mid-stream is often worse. ...
The book provides practical guidance for analysts at all experience levels; from the first steps of how to apply the technique of GC-MS from collecting and preparing samples to designing and validating methods, analysing results and troubleshooting. ...
The book is a useful reference guide for analysts at all experience levels with practical guidance on the steps of how to apply the technique of GC-MS, from collecting and preparing samples to designing and validating methods, analysing results and troubleshooting. ...
The application of the Anionic Pesticides Explorer has enabled us to enhance the productivity of our testing workflows through the reliable detection of multi-residue pesticides across a wide range of sample matrices, all within a single, sensitive analytical solution." The Anionic Pesticides Explorer is designed to provide food testing laboratories with: Increased workflow ...
The advertisements issued by the Ministry of Housing and Urban Affairs under SBM, featuring actor Amitabh Bachchan, also appears to be pushing composting machines instead of traditional methods. In the absence of guidelines, claims by manufac turers have become the standard. ...
Determination of chromium in complex matrices is a notorious challenge, as interconversions between species may occur during sample preparation, making quantification very difficult. In a recent research study published in Journal of Agricultral and Food Chemistry, Rahman et al. performed speciated isotope dilution mass spectrometry (SIDMS), as described in ...
For this reason, fast analysis methods of quality parameters such as nicotine, glycerin, and water in e-liquids are trendsetting and already required. A very suitable solution is the use of visible near-infrared spectroscopy (NIRS), which enables simultaneous real-time quantification of nicotine and glycerin without sample preparation. Another ...
One of the biggest challenges for laser diffraction methods is getting a representative sample out of a larger bulk product. ...
Thermo Fisher Scientific is supporting regulatory laboratories, contract research organizations and licensed dealers, producers and suppliers across this emerging sector with a diverse and comprehensive product portfolio that offers complete workflows, from sample preparation to analytical methods, for the analysis of cannabis matrices to the ...
Lumex Instruments is pleased to announce the workshop series about Universal Direct Mercury Analysis of a wide range of samples: Fast and Simple Mercury determination without reagents and sample preparation. In these workshops, Lumex Instruments’ experts will discuss the advantages of atomic absorption spectroscopy with Zeeman background ...
