Description

Type: ISA Solution
For Use With (Equipment): Calcium Electrode
Quantity: 475 mL
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 the purpose of calcium ISA?

Answer:It is added to samples and standards to create a uniform ionic-strength background for more reproducible calcium ISE measurements.

Question: What volume is supplied?

Answer:The bottle contains 475 mL.

Question: Which electrode is this reagent intended for?

Answer:It is intended for calcium ion-selective electrode measurements.

Application Note

Orion™ Calcium Ionic Strength Adjustor 932011 is used to condition calcium samples and calibration standards for reproducible ion-selective electrode measurements. A fixed amount of ISA is added to every standard and sample so that background ionic strength remains consistent across the calibration curve and unknowns. This reduces changes in ion activity caused by differences in sample matrix and improves the relationship between calcium concentration and measured electrode potential. The reagent is supplied as 475 mL in one bottle and is intended specifically for calcium ISE workflows. The solution contains a high concentration of potassium chloride, providing the ionic-strength background required by the method. Used together with the Orion calcium electrode, filling solution, and calibration standards, the ISA forms part of a complete potentiometric measurement system for routine laboratory, water, and process analysis.
