Conductivity stopped flow
Product Codes: OPT-642 (for SF-61SX2 and DX2 systems)
Conductivity is suited to reactions that exhibit an ionic change and these may include metal ligand binding, micelle formation, proton exchange, ion exchange and reduction/oxidation reactions.
It comprises a conductivity mixing cell and accompanying conductivity meter. The mixing cell is installed on the sample handling unit with its associated electrode cables connecting it to the conductivity meter. This mixing cell is supplied in lieu of an optical cell for dedicated conductivity systems or an option for the user to change as required.
The conductivity mixing cell has a T-format mixer and features a cylindrical cavity in a PEEK block. The ends are closed by platinum electrodes. The cell volume is 21 ul, with a nominal cell constant 4.24 cm-1. The precision machined and finished cell housing acts as an effective EMI/RFI shield. The interface to the sample handling unit makes the reagent connections easy and also connects the thermostat circuit thus enabling temperature control, with a 5-60 °C range.
A conductivity meter provides the excitation signal and an output directly proportional to conductivity. This meter has six switched ranges allowing the user to measure conductivities from 5×10-6 S to 0.25 S.
The conductivity detection is supported within Kinetic Studio software enabling the user to report data in conductivity units. Kinetic Studio provides for data acquisition and analysis as well as full instrument control of the sample handling, operating in both single and double mixing modes.
