Is GCMS expensive?
The running costs are negligible for both, so you only need to consider the cost of the the equipment., and generally GCMSs are much more expensive than HPLC. Normally, GC-MS, LC-MS are costlier than HPLC.
HPLC solvents are costly in comparison to gases used for GC analysisGC analysisGC is very accurate if used properly and can measure picomoles of a substance in a 1 ml liquid sample, or parts-per-billion concentrations in gaseous samples.https://en.wikipedia.org › wiki › Gas_chromatographyGas chromatography - Wikipedia. In addition to cost of solvents the maintenance cost of High Performance Liquid Chromatography systems is also higher due to high pressures developed in pumps and columns. GC analysis in comparison is less costly and there is lesser maintenance cost.
