Data Analysis, Statistics, and Chemometrics

This article will explore what is meant by "complete data" in the context of a chromatography data system and, with an analysis of FDA 483 citations, explore the problems when a laboratory fails to understand this phrase.

The requirements for GPC/SEC data analysis to obtain precise, reproducible and accurate results are very specialized. Therefore, often dedicated software tools offering flow-rate correction or different calibration options need to be employed. This instalment of Tips & Tricks looks at these requirements.

This new data-management method is specifically designed to handle the large amounts of data produced in proteomics studies. Experimental methods and data are presented from a recent study conducting proteomics profiling of Schizosaccharomyces pombe to demonstrate the effectiveness of the data management solution. The results demonstrate enhanced data search speeds as well as effective data analysis.

Part two of the column on response surface designs looks at data analysis and various approaches to simultaneously optimize multiple responses

HPLC with ELSD continues to grow in popularity as a "quasi- universal" detector. Improvements in ELSD instrument design, including low temperature evaporation, have recently been commercialized...

Part I of this series of articles provides an overview of a chromatography data system, including the life cycle, key functions, and problems.

Data management using database management system software has become a mainstream desktop application because of its ease compared with spreadsheet programs.
