Thermo Scientific Orion® ISE Ionic Strength Adjustors (ISA) and Special Reagents

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.

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 (246-25369) and low-level ammonia pH-adjusting ISA (666-10105) 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 (246-25369) 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 (666-10105) 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:
• Cat. No. 246-25225 is packaged as two 1 quart (2 x 1L) bottles
• Cat. No. 246-25204 is packaged as four 1 pint (4 x 475mL) bottles
• Cat. No. 246-25171 is packaged as one 1 gallon (3.7L) bottle
• Cat. No. 246-25180 is packaged as four 1 gallon (4 x 3.7L) bottles
