Titralab 870 法国Titralab 870 自动电位滴定仪的详细介绍
Potentiometric methods
- End point titration: 1 to 4 pre-set end points.
- Inflection point titration: auto determination of 1 to 8 inflection points, programmable IP acceptation windows.
- Titrant addition techniques: incremental dynamic, incremental monotonic and continuous dynamic.
- Method reprocessing for curve and results: automatic or manual.
- pH electrode calibration: up to 5 points using IUPAC standards or 4-7-10 Series buffers with error recognition on buffer used.
- pH with temperature-compensated reading: probe, entered or fixed at 25°C.
- Direct pH/mV measurements with recording on stable reading.
- Back titration: manual or automatic.
- Reagent addition: up to 3 simultaneous or consecutive additions.
- Sequencing of up to 10 methods, including electrode and reagent calibrations.
- Coupling of 2 to 6 methods in one beaker, including direct ISE and EC measurements.
Conductivity method (EC)
- Direct conductivity measurements with recording on stable reading.
- Conductivity with temperature-corrected display: none, natural water (ISO 7888), linear.
- Conductivity cell cable resistance and capacitance compensation.
- Conductivity electrode calibration: manual cell constant entry or automatic determination using 1, 0.1 and 0.01 Demal KCl standards, NaCl 0.05% and standard sea water.
Ion-Selective Method (ISE)
- ISE measurements using standard additions or direct measurements with recording on stable reading.
- Additions or calibration with up to 9 points.
Curves fitted using non-linear regression with CØ detection limit determination according to IUPAC.
- Automatic standard additions: volumes programmed or automatically determined.
- Curve plotting: GRAN plot vs. Volume for standard additions, mV = f(pC) for ISE calibration.
