Control of Tailing and Listing Problems in Continuous

Tailing and listing problems can be caused by two controlling factors, namely: Equipment parameter changes or variations or Barium number To check the degree of mercerising; sampling at 2000–3000 m intervals. Shows the absorbency variation across the Get price

Trace Analysis Guide

The concern is that tailing from the larger peak into the smaller peak will occur, giving false high results for the smaller peak. I personally experience this problem on a daily basis while attempting to measure ppb to ppt levels of impurities in our products that are typically diluted to 100 - 200 g/g for ICP-MS trace impurity analysis.
