Description

• Prior to first use, rinse the electrode with distilled water and soak it in the appropriate standard for 24-48 hours and then fill with reference electrolyte (refer to table above)
• ISA (Ionic strength adjuster) solution required to be added to all calibration standards and samples prior to measurement for accurate results
• Refer to electrode user manual for appropriate ratio of ISA solution to sample volume
• Add filling solution each day before using the electrode (at least 2.5 cm above sample level in beaker)
• Be sure to screw cap tightly immediately after use
• The filling solution inside the electrode should not be allowed to evaporate, as crystallization will result
• For storage between measurements and up to three days, store in the appropriate standard
• For long-term storage, refer to specific ISE electrode user manual
• Sensing membrane will wear over time; each membrane can last about six months with normal use, but actual lifespan will depend on the type of samples that are being measured
• Competing ion interferences are common. Refer to ISE electrode user manual for potential interferences
• Compatible with METTLER TOLEDO SevenExcellence Benchtop, Seven2Go, and SevenGo Portable
• Compatible with InMotion Autosampler to automate measurement and cleaning of up to 303 samples
