Calibration refers to the process of determining the relation between the output (or response or signal) of a measuring instrument and the value of the input quantity or property. Depending on the univariate or multivariate character of the response (signal) used; either a univariate or a multivariate calibration is performed. The different calibration approaches are summarized in this article.

Electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI) are now among the most commonly used techniques for creating ions, especially from small-molecule compounds in solution. They have become so familiar that now many articles only refer to them briefly. Yet each technique has dramatic predictive strength on the outcome and limits of an analysis.

Accurate preparation and correct selection of buffers is essential to obtain reproducible and consistent results in capillary electrophoresis (CE). A number of factors should be considered in buffer optimization, including the pKa of the buffering ion and the analyte as well as the molarity of the acid or base used in the adjusting procedure. Accurate recording of the precise reagents used and the procedures performed is necessary to prepare buffers consistently.

Editor Dave Walsh suggested that current columnists for LCGC might enjoy writing about their experiences in writing their columns and relate how they got into such writings and where it has taken them.

While most chromatographers would agree that development of effective, short, and stable chromatographic methods requires elements of personal intuition and systematic screening, some might argue that it is in fact more art than science.

CDS Analytical, Inc. has been a leader in the design and manufacture of laboratory instruments for sample preparation and analysis for over 35 years.

Today, the ESA name is synonymous with innovation in HPLC detection. But our roots in this market go back 25 years, when we launched a groundbreaking electrochemical detector (ECD) in a brand new magazine: LCGC North America.

When Peak Scientific started manufacturing gas generators in 1997, we knew that there was a huge potential for our gas generation products, which include nitrogen generators for LC–MS as well as hydrogen, ultra high purity nitrogen, and zero air generators for GCs. 10 years later, we are still amazed by the rapid growth of the market not only for gas generator products but also for those instruments that require gas to analyze samples, such as LC–MS and GC.
