These chemicals are used to dissolve, condition, react with, carry, deposit, position, or otherwise modify the sample to prepare it for analysis. Few instruments are alike; they vary considerably in the volume of reagents required, the number of reagents, the chemical composition of reagents, and in the relative lifetime of reagents.
Instruments may also differ substantially in how they control, segment, and steer reagents in addition to how they cycle between those reagents during an analytical process. As with samples, the quality of analysis often depends on how carefully and reproducibly reagents are moved through the instrument. Often, instruments are particularly sensitive to the relative carryover generated between sequential reagent applications.
We know you need to get fluids to the right place at the right time, and usually removed when you are finished with them. We are leaders in preventing carry-over and work very closely with customers on reagent retention problems. Proper flow path design requires evaluation of internal passageways, compatibility of wetted materials, and geometrical pathway optimization –all core areas of expertise for IDEX Health & Science.
