Companies like Hewlett-Packard (now Agilent Technologies) and PerkinElmer developed robust and reliable GC-MS systems, making the technology more accessible to researchers and industries. ...
At the end of the day always flush the system with water and solvent. This will prevent salt precipitation, damage to the instrument seals and leaks within the system.A4. ...
Ion chromatography and sample filtration go hand-in-hand since this pretreatment step is advised for the majority of sample matrices. It is essential to avoid injecting particles, algae, or bacteria into the IC system, as these can jeopardize both the instrument and the separation column. Samples are often prepared manually, for example by using filtration or centrifugation to remove contaminants ...

Can I let you in on a secret? Your current method of measuring dioxins is probably not giving you the whole picture about your dioxin emissions. A typical waste incineration plant will run for about 8000 hours per year. Many waste incineration plants are still using the old method of periodic sampling. With periodic sampling, dioxins are only measured for 6-8 hours at a time. You don’t need ...
It all began in the 1950s with a pioneering article by Alan Walsh. Today, it is an established standard technology in the field of analytical chemistry: atomic absorption spectrometry (AAS). AAS has experienced amazing development through the decades. In addition to newer ICP technologies, modern AAS systems such as Analytik Jena’s contrAA 800 exist thanks to ongoing technological ...
Abstract This application note demonstrates a multi-step thermal extraction study on Tetrahydrocannabinol (THC) vape oils. Introduction E-cigarettes have gained popularity in recent years, in conjunction with the legalization of marijuana in many U.S. states. Authentic THC vape oils are not easily distinguishable from the counterfeits, which are poorly regulated and can cause severe lung ...
Senior Application Chemist at Shimadzu (Asia Pacific) PTE Ltd, Ting Zhi Wei Edwin, uses Peak Scientific gas generators to support his LC-MS instruments. Find out his experience with Peak's generators and how his lab has benefited from being [Peak Protected] Name: Ting Zhi Wei Edwin Job Title: Senior Application Chemist Company: Shimadzu (Asia Pacific) PTE LTD Peak Scientific has installed ...
To increase the throughput of our existing mAb purification protocol we coupled an NGC Discover™ Pro Chromatography System to a Teledyne CETAC ASX-560 Autosampler. The NGC™ Discover Pro System's multidimensional (Multi-D) chromatography function allows automated multicolumn purification workflows while the ASX-560 ...
SFA’s are also highly automated and once the analyzer is configured and the reagents and samples are loaded, reliable unattended operation is a major benefit. A basic SFA system consists of an autosampler, a peristaltic pump, a chemistry manifold, a detector and AACE data acquisition software. ...
To cope with a sample load of up to 120 samples a day the equipment used must be fully automated. The complete system com-prising the Digest Automat K-438, the KjelMaster K-375 and the KjelSamper K-377 allows to reduce user interaction during analysis to a minimum. ...

Abstract In developing the Atomx Automated Sample Prep System, Teledyne Tekmar integrated both a P&T concentrator and a multi-matrix autosampler into a single platform system that can be used in the analysis of soil, water, and soils requiring methanol extraction. ...
Thermo Fisher Scientific, Inc. exhibited its Next-Gen Mining portfolio during MINExpo 2012 in Las Vegas, September 24-26. The company’s highly integrated range of instruments, equipment and consumables, anchored by its industry-leading laboratory information management systems (LIMS), is the only offering that addresses all segments of the mining process, from early stage exploration ...
From the earliest days of digging into the earth for minerals, one question has been raised by all those seeking to make use of the materials the earth offers up: what exactly have we dug up and is it what we hoped it would be? Well we’re not panning for gold anymore and hoping for a glint of something shiny at the bottom of our pans, unless we hobbyists. Modern mining operations have ...
The use of an ESI SC FAST autosampler coupled to a Perkin Elmer Optima 7300 DV ICP can dramatically improve productivity for the analysis of environmental samples using EPA SW-846 Method 6010C. Sample throughput, as determined by sample-to-sample run time can be improved by as much as 100% as compared to traditional sample introduction systems and ...
The application of an SC-FAST sample introduction system to the analysis of natural and certified water samples is described. The SC-FAST system consists of an autosampler, sample loop, switching valve, high efficiency nebulizer and a glass cyclonic spray chamber to perform analysis by direct nebulization. The potential benefits of this ...
Sample introduction was accomplished with an Elemental Scientific, Inc. sampler changer SC-FAST sample introduction system. Instrumental conditions for the ICP-MS and SC-FAST, as well as experimental parameters used throughout this work, are presented in Tables 2 and 3 (Pages 3 and 4). The SC-FAST is a sample introduction system consisting of an ...
Laboratories monitoring trace level pesticides and herbicides by gas chromatography/mass spectrometry (GC/MS) frequently utilize Selected Ion Recording (SIR) techniques to maximize analytical sensitivity for quantification. With analytical standards, precision is limited to a large extent only by the autosampler and other instrumental effects. However, real-world samples pose a greater challenge. ...
The application of an SC-FAST introduction system to the analysis of natural and certified water samples is described. The SC-FAST system consists of an autosampler, a switching valve, a high efficiency PFA-ST nebulizer and Peltier-cooled cyclonic spray chamber to perform analysis by direct nebulization. The potential benefits of this ...
