Cadmium ion electrode 8007-10C Instruction Manual
| Measuring range | 0.1 to 11,240 mg/L Cd2+ (10-6 to 10-1 mol/L) Cd2+ |
|---|---|
| pH range | 11 mg/L (10-4 mol/L) Cd2+ pH 3 to 锛� |
| Applicable temperature range | 0 to 50鈩� |
| Response time (90%) | Within 10 seconds |
| Applicable reference electrode | 2060A, 2565A |
| Selection coefficient | Cu2+銆丠驳2+Ag+ = Not acceptable Pb2+ = 0.1銆�Fe3+ = 1 Cr3+銆丗别2+ = 100 Ni2+ = 1,000 |
鈥� The response time is the time which is required to reach 90% response when the ion concentration is gradually changed from 10-4 mol/L to 10-2 mol/L with the solution stirred.
Exception:
*1: 90% response when ion concentration is changed to 10-6 mol/L 鈭� 10-2 mol/L
*2: 95% response when ion concentration is changed to 10-3 mol/L 鈭� 10-1 mol/L
*3: 95% response when ion concentration is changed to 10-4 mol/L 鈭� 10-2 mol/L
*4: 95% response when ion concentration is changed to 10-4 mol/L 鈭� 10-1 mol/L
鈥� The selection coefficient is a ratio of the limit concentration of coexisting ions (mol/L) to the ion concentration to be measured (mol/L); The value of 1000 means that the coexisting ions can be permitted up to 1000 times the ion measured and ''not acceptable'' means that chemical change occurs in the solid response membrane.
