During the last several years, the GC market has experienced strong growth in part because of new product introductions, growth in the petroleum sector, and increased opportunities in various geographies. To shed light on and determine the many realities and trends of the current GC instruments market, Strategic Directions International conducted a global survey of gas chromatography (GC and GC-MS) users. The survey was designed for individuals who are currently using a wide array of GC instruments and consumables, including aftermarket software, components, and accessories. The data were collected over the phone and by an internet-based survey. When necessary, the internet survey was followed up with direct telephone interviews of the appropriate respondents to further clarify answers.
