Take more accurate and reproducible ISE measurements with Orion™ ISE Ionic Strength Adjustors (ISA) and Special Reagents.


  • Uniform background ionic strength
  • Accurate results
  • Free from metal interferences


Ionic strength adjuster is added to all samples and standards to create a uniform background ionic strength, which provides more reproducible measurements. For example, 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 complextion 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 10 ppm and below that do not contain metal interferences.


Ionic strength adjustors are used for analysis with ion selective electrodes, and special reagents are used with some ion selective electrodes.
