An essential guide to the proven automated sample preparation processWhile the measurement step in sample preparation is automated, the sample handling step is manual and all too often open to risk and errors. The manual process is of concern for accessing data quality as well as producing limited reproducibility and comparability.Handbook of Automated Sample Preparation for CG-MS and LC-MS explores the advantages of implementing automated sample preparation during the handling phase for CG-MS and LC-MS. The author, a noted expert on the topic, includes information on the proven workflows that can be put in place for many routine and regulated analytical methods.This book offers a guide to automated workflows for both on-line and off-line sample preparation. This process has proven to deliver consistent and comparable data quality, increased sample amounts, and improved cost efficiency. In addition, the process follows Standard Operation Procedures that are essential for audited laboratories. This important book: Provides the information and tools needed for the implementation of instrumental sample preparation workflowsOffers proven and detailed examples that can be adapted in analytical laboratoriesShows how automated sample preparation can reduce cost per sample, increase sample amounts, and produce faster resultsIncludes illustrative examples from various fields such as chemistry to food safety and pharmaceuticalsWritten for personnel in analytical industry, pharmaceutical, and medical laboratories, Handbook of Automated Sample Preparation for CG-MS and LC-MS offers the much-needed tools for implementing the automated sample preparation for analytical laboratories.

Hans-Joachim Hübschmann graduated as Certified Food Chemist from the Technical University in Berlin, Germany, working on residue analysis of anabolic agents and pesticides in foods. He started his career in diagnostics, medical analytical instruments and application development working for a number of German companies in chromatography, mass spectrometry and in biotechnology. He joined Thermo Fisher Scientific in Bremen, Germany, and held several international positions covering inorganic and isotope ratio mass spectrometry specializing in food safety, forensic and dioxin analysis. In 2015 he established the independent consulting agency HANS Analytical Solutions for the development of automated sample preparation workflows. In his current capacity he is located in Osaka, Japan, as the Vice President Sales of CTC Analytics for the emerging Asia/Pacific region.
