Description

Type: TISAB II
For Use With (Equipment): Fluoride Electrode
Quantity: 1 Gal.
Unit Size: Each
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:
• Cat. No. 941709 is packaged as two 1 quart (2 x 1L) bottles
• Cat. No. 941609 is packaged as four 1 pint (4 x 475mL) bottles
• Cat. No. 940909 is packaged as one 1 gallon (3.7L) bottle
• Cat. No. 940999 is packaged as four 1 gallon (4 x 3.7L) bottles

FAQs

Question: What is TISAB II used for?

Answer:It controls ionic strength and pH and helps reduce fluoride-complexing interference during fluoride ISE measurements.

Question: What quantity is supplied?

Answer:This configuration contains 1 gallon, approximately 3.8 L.

Question: How is TISAB II commonly mixed with samples?

Answer:Routine fluoride methods commonly use a 1:1 mixture of sample or standard with TISAB II.

Application Note

Orion™ TISAB II is a total ionic-strength adjustment buffer for fluoride ion-selective electrode measurements. This configuration contains one gallon, approximately 3.8 L. The reagent is mixed with fluoride standards and samples to establish similar ionic strength, buffer the solution to a suitable pH, and reduce interference from metal ions that can complex fluoride. TISAB II is commonly used at a 1:1 ratio with the sample or standard in routine fluoride ISE methods. Consistent use improves calibration reproducibility and helps the electrode respond primarily to free fluoride activity rather than uncontrolled matrix differences. The large-volume format is useful for laboratories performing routine fluoride analysis in drinking water, wastewater, industrial samples, food, minerals, and related matrices.
