Measurement stability in complex and challenging matrices is important alongside instrument uptime and a reduction in user maintenance. The Thermo Scientific™ iCAP™ PRO Series ICP-OES incorporates a vertical torch design, providing not only the smallest footprint ICP-OES on the market but also delivering unchallenged robustness. A vertical torch orientation for a radial-only instrument is the industry standard; however, for a dual view instrument there are two major challenges that need to be addressed to ensure robustness. The first of these challenges is the deposition of sample matrix on the plasma interface, and the second is corrosion of the interface parts due to the introduction of potentially higher matrix samples. Both can lead to contamination, increased instrument maintenance, and high costs for replacement parts or servicing of the instrument. To reduce instrument downtime, the maintenance of the instrument should be easy to perform and as infrequent as possible.
