In this month's installment, we look at the results of a recent survey on high performnace liquid chromatography (HPLC) columns, examining the trends in analytical and preparative column use and purchasing patterns since the last survey. Factors investigated in this study were mode and stationary phase usage, particle sizes and column dimensions, column budgets, and the factors influencing buying decisions. Column lifetime and use of guard columns also is considered. Future column buying plans were explored.
