Take more accurate and reproducible ISE measurements with Thermo Scientific™ Orion™ ISE Ionic Strength Adjustors (ISA) and Special Reagents. Ionic strength adjustors are used for analysis with ion selective electrodes, and special reagents are used with some ion selective electrodes.
Warranty: Out of box
Ionic strength adjuster is added to all samples and standards to create a uniform background ionic strength, which provides more reproducible measurements. The ammonia pH-adjusting ISA (951211) and low-level ammonia pH-adjusting ISA (951210) both include a pH-indicating blue dye for instant verification of correct pH in ammonia samples and standards with no pH measurement required. The ammonia pH-adjusting ISA (951211) prevents complexation of ammonia and inhibits formation of metal hydroxides, allowing determination of total ammonia in the sample and increasing the accuracy of results. The low-level ammonia pH-adjusting ISA (951210) is ideal for ammonia samples with a concentration of 10ppm and below that do not contain metal interferences.
All ionic strength adjusters and special reagents are packaged as one 1 pint (475mL) bottle, except:
