Advantage of Premixed Mobile Phases for Consistent Chromatography of Peptides Using Nano-LC–MS/MS
May 1st 2017High resolution mass spectrometry with nano-LC is used for protein identification and quantification in both top-down and bottom-up proteome analysis. Reliable instrumentation in combination with ultrapure mobile phases is essential for data integrity. Premixed 80% acetonitrile with 0.1% formic acid (LS122-500) and water with 0.1% formic acid (LS118-500) were designed to produce a consistent chromatographic performance using this instrument system. In this study, these mobile phases were used extensively to evaluate several factors which can affect separation of protein digests such as peak retention, peak repeatability, and sample carryover. Our results demonstrated excellent chromatographic performance using Thermo Scientific EASY-nLC 1200 LC system and Thermo Scientific LTQLX ™ ion trap mass spectrometer with the specialized premixed mobile phases.
Current Trends in Food Analysis
August 11th 2016In recent years, food analysis has blossomed out from a singular focus on food safety to a studies of a wide array of questions such as the authentication of food origin and the nutritional aspects of natural food compounds. In this new e-book, we explore some current trends in food analysis and also provide some concrete advice for preparing food samples for analysis.
Advancing GC Methods and Environmental Analysis
May 13th 2016Gas chromatography (GC) is a powerful technique for environmental analysis. The articles in this new e-book look at both the technique and its application, providing essential information about GC fundamentals as well as an example of how the technique can be used in new ways in environmental analysis.
Technological Developments in Ion Chromatography
May 6th 2016In this Q&A, we will talk to Dr. Arthur Fitchett, Director of Sales Training at Thermo Fisher Scientific. We will discuss recent advances in ion chromatography technology, what they mean for different types of IC analyses, and how they can improve results in your laboratory.
Development Partners for BioPharma
April 27th 2016Your current contract laboratory and instrument provider may be familiar and comfortable, but, maintaining the status quo doesn’t lead to greater rewards. In fact, it often involves putting up with less-than-desired results. Join us in this executive summary to hear how Ajinomoto Althea develops unsurpassed solutions for biopharma companies, and how a team at Thermo Fisher Scientific has challenged the status quo to deliver uncompromised UHPLC.
Fast, Cost-Effective IC Methods for Testing Environmental Waters
April 7th 2016Ion chromatography (IC) is a well-established technique for monitoring inorganic anions in environmental waters around the world. It is approved by the U.S. Environmental Protection Agency (U.S. EPA) for compliance monitoring of primary and secondary inorganic anions in drinking water and has been validated by European standards organizations, including the International Standards Organization (ISO). These agencies have published IC methods for the analysis of inorganic anions in drinking water, groundwater, and wastewater. These methods can be made faster and more cost-effective, however, by using the latest IC technologies, including high-pressure IC. In this summary, we will discuss regulatory compliance testing of municipal drinking water and wastewater, and how this testing can be made faster and more cost-efficient through the use of high-pressure-capable ion chromatography systems.
Looking for What We Know About and What We Don’t in Drinking Water
April 1st 2016This summary will explore the latest developments in the analysis of contaminants of emerging concern in drinking water. We will explore the requirements and results from the EPA’s Unregulated Contaminant Monitoring Rule 3 program for Perfluorinated organics, and hormones. After a brief overview of the EPA analytical techniques, we’ll take a look at new technology and ask how it compares for both and if it can find compounds we didn’t even know were there.
