WebAs shown in Figure 4, good reproducibility of retention times can be achieved by using J&W PLOT PT columns. RSD obtained from 250 replicate analyses of standard gas mix was found to be below 0.06%. This showed that excellent repeatability (intra-day) and long-term precision (inter-day) was achieved using the J&W PLOT PT columns. WebRetention of target compounds is not influenced by water in the sample Long-term stability provides repeatable retention times Available in Fused Silica and UltiMetal Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency Performance Summary shipped with each column
