Product details
Calcium combination electrode hanna hi4104
The HI-4104 Calcium Ion Selective Electrode is a complete potentiometric cell that contains a Silver/Silver Chloride (Ag/AgCl) reference housed within a PEI plastic body with a Potassium Chloride electrolyte. The internal elements are isolated from the sample by an organic polymer sensing membrane. Hanna’s liquid membrane combination ISEs are designed with a cone style junction.
Before testing, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the ionic strength adjuster (ISA) solution (HI-4000-00). The HI-4104 calcium liquid membrane ISE can measure from 3µM (0.12 mg/L) to 1M (40,080 mg/L).
