Managing Heterogeneity with Incremental Sampling Methodology
November 1st 2017Incremental sampling methodology laboratory processing is used to produce an appropriately sized subsample that has the analytes of interest at the same concentration as the large incremental sample collected in the field. The end goal is to produce results that represent the conditions at the site and facilitate good decisions.
A New Twist to Ion-Pairing Chromatography: In-Sample Addition of Ion-Pairing Reagent
November 1st 2017Ion-pairing chromatography has traditionally been implemented with the addition of an ion-pairing reagent into the mobile phase. Here, an alternative method is presented, in which the ion-pairing reagent is deposited on column as a sample additive instead of in the mobile phase.
