Standardization of gas chromatographic methods and requirements can be a very good thing. I will bet that you noticed, just as I did, that when you implement new methods they cause unintended consequences in the rest of the lab. When I first started running gas chromatographsand GC-MS in the laboratory we did all we could to try to meet method requirements. I would complain about having to meet specific requirements because they would cause me problems in some other part of my work. For instance, extractions needed to be done differently, internal standards were to be added at a different point in the preparation, new reports needed to be created, QC requirements needed to be learned, and probably have to buy new GCs with a new configuration. It was not just the method or meeting the QC requirements. The efficiency of the laboratory was impacted for quite some time. This is more than method development. This is decreased efficiency and increased cost in the gas chromatography lab.
Method development and regulating bodies such as American Society for Testing and Materials (ASTM) and European Committee for Standardization (CEN) can dictate the method, certainly the instrumentation, and reporting for a sample matrix and analytes. When gas chromatography methods are adopted by a laboratory it is common to just try to add that functionality. Although this works it adds complication to the laboratory and complication is inefficiency. As a new method or functionality is added to a gas chromatography laboratory Users will frequently create a system that is neither efficient nor automated by combining multiple instruments for sample preparation, injection, and acquisition, with difficult, time-consuming post-processing calculations and custom reporting.

True laboratory productivity is only achieved by integrating the capabilities of a chromatography data system that controls multiple hardware platforms, and offers powerful data processing tools, with the recent improvements in GC instrumentation design that extend the capabilities of GC laboratories. In this webinar, we present new methodologies for tailoring the software and hardware configuration to the application. These streamlined environmental and petrochemical workflows automate sample preparation and all the software operations, such as integration, calibrations, and calculations to deliver ease-of-use and laboratory productivity.
