Our new polymer and deactivation chemistries produce highly inert columns with tightly controlled selectivity resulting in exceptional performance for a wide range of analytes (acidic, basic, and neutral).<\/p>\n\n\n\n<p>Rxi-SVOCms columns are tuned specifically to improve peak shape for challenging SVOCs, such as pentachlorophenol, pyridine, and benzidine, as well as to ensure optimized resolution of difficult polycyclic aromatic hydrocarbons (PAH). As shown in Figure 1, the most problematic reactive analytes show highly symmetrical peak shapes and good responses. In addition, excellent resolution (\u226585% valley) is obtained for benzo[b]fluoranthene and benzo[k]fluoranthene, which are isobaric PAHs that must be separated chromatographically, as well as for indeno[1,2,3-cd]pyrene and dibenz[a,h]anthracene.<\/p>\n\n\n\n<p>For chemists in the environmental industry who are slowed down by variable column performance, frequent calibration failures, and poor column lifetimes, switching to rugged Rxi-SVOCms columns can ensure data requirements are met longer and downtime is minimized.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 1:<\/strong>\u00a0Rxi-SVOCms columns provide outstanding chromatographic performance, reliably producing good peak shape and resolution even for problematic compounds. Split injection is recommended, when possible, because is minimizes the effect of inlet contamination on transfer of sample to the analytical column.<\/div><div

The improved inertness of Rxi-SVOCms columns overcomes this, resulting in an average response factor %RSD from the initial calibration of six columns of just 6% over all compounds and columns (Table I). Extremely low and consistent response factors ensure that calibrations will last longer, allowing more samples to be run before recalibration is required. As shown in Figure 2, consistent peak shapes and retention times are seen even across different concentrations of pyridine and pentachlorophenol, which are problematic compounds that tend to tail and often fail calibration criteria on columns that are not highly inert.<\/p>\n\n\n\n<p><strong>Table I:<\/strong>&nbsp;Stable performance means fewer recalibrations and more time available for running samples, which improves lab productivity.

Improved column chemistry ensures that Rxi-SVOCms column performance is durable even under very aggressive conditions. In Figure 3, we subjected columns to repeated injections of a dirty sample, monitored calibration performance, and cut off contaminated sections after every 30 sample injections. Even after 300 injections, performance was easily restored with a quick column trim as evidenced by fewer than 10% of compounds failing the post-trim calibration check. Bringing back performance with simple routine maintenance means more samples can be analyzed with less downtime and fewer column replacements.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 3:<\/strong>\u00a0Column performance is completely restored by trimming following repeated exposure to a highly complex sample.
