Ionic strength adjustors are used for analysis with ion selective electrodes, and special reagents are used with some ion selective electrodes.
- Ionic strength adjuster is added to all samples and standards to create a uniform background ionic strength, which provides more reproducible measurements
- Ammonia pH-adjusting ISA and low-level ammonia pH-adjusting ISA both include a pH-indicating blue dye for instant verification of correct pH in ammonia samples and standards with no pH measurement required
- Ammonia pH-adjusting ISA prevents complexation of ammonia and inhibits formation of metal hydroxides, allowing determination of total ammonia in the sample and increasing the accuracy of results
- Low-level ammonia pH-adjusting ISA is ideal for ammonia samples with a concentration of 10 ppm and below that do not contain metal interferences
