Ammonia ISE 1000 ppm Standard, Hanna Instruments, HI4001-03

Hanna Instruments® Ammonia ISE 1000 ppm Standard, HI4001-03

Features:

• Appearance: colorless liquid
• CAS Nos.:  standard does not contain hazardous materials
• Premium quality 1000 ppm (mg/L) ammonia standard solution (as NH₃-N)
• Lot number and expiration date clearly marked on label and in air tight with a tamper-proof seal to ensure quality
• Specially formulated to have expiration of 5 years from date of manufacture for an unopened bottle
• Used to calibrate ammonia gas sensing, combination ion selective electrode (ISE)
• ISEs require calibration for accurate readings when performing measurement techniques such as direct measurement and incremental methods
• Calibration of up to two points is recommended for enhanced accuracy
• Volumetric glassware can be used to make dilutions of standard solutions to bracket expected concentration of sample to be measured
• ISE calibration standards and sample solutions should always have same ionic strength; exact volume of ionic strength adjuster (ISA) must be added to all standards and samples prior to measurement
