Consistent Consumable Quality Improves CHN Microanalysis Results
Consistent Consumable Quality Improves CHN Microanalysis Results
Exeter Analytical
28/10/2014

Exeter Analytical reports on how the consistency and quality of routine microanalysis consumables can have a significant effect on the variability of determined percentage carbon, hydrogen and nitrogen (CHN) results.An existing user of an Exeter Analytical Model 440 CHN analyser, driven by tight budgetary considerations, elected to try to save some money by buying consumables from a non-certified supplier. However after a few weeks they noticed that blank carbon and...
