If there was a method for packing material manufacturers to specify shape characteristics and for column manufacturers to inspect incoming materials against those specifications, manufacturing HPLC columns would become more predictable, less costly and exhibit consistent performance. Recent advancements in image analysis could provide the answer.
Sampling using sorbent tubes for analysis by thermal desorption gas chromatography is ideal for a wide range of applications, from monitoring industrial air to odor profiling of foods. However, for those new to the area, the options available can make it difficult to decide how best to proceed.
