ExperimentMeasureConductivity

ExperimentMeasureConductivity[Samples]Protocol

generates a Protocol to measure conductivity of the provided Samples.

    
Electrical conductivity meter (EC meter) measures electrical conductivity in µS/cm by immersing conductivity probe in a solution. The EC meter applies an alternating voltage at an optimal frequency on the probe sensor and measures the size of the resulting signal (depending on the probe type), which is directly related to the conductivity. During this process, the cations migrate to the negative electrode, the anions to the positive electrode and the solution acts as an electrical conductor. The more free anions and cations the liquid contains, the higher the electrical conductivity. Conductivity measurement is a rapid and inexpensive way to monitor the ionic content in a solution, for instance the measurement of the amount of nutrients, salts or impurities in water.
    

Experimental Principles

    Figure 1.1: Figure 1.0: Procedural overview of a MeasureConductivity experiment. Step 1: During the first step, the conductivity Probe is calibrated. Step 2: Based on the specifications, the probe is primed with a rinse sample before testing, if RinseSample->True.Step 3: Probe is then introduced into the sample and electrical conductivity is measured. Step 4: After the final sample measurement, the Probe is cleaned and stored.

Instrumentation

    SevenExcellence Conductivity

    Figure 2.1: The conductivity probe is immersed into the sample.Depending on the customer's needs there are two different types of the probe available at the ECL facilities. AmperometricSmallSampleVolume (2 electrodes) probe is suitable for the low volume samples (150 uL minimum).Potentiometric Regular (4 electrodes) probes have higher accuracy and wider conductivity range but require minimum of 5 mL sample volume.Conductivity meter applies an alternating voltage on the probe and measures the resulting signal:amperometric or potentiometric,depending on the probe type.Taking into account probe calibration the resulting signal transforms to the electrical conductivity output readings.

Possible Issues

    Minimum Sample Volumes

    Each conductivity probe requires the fluid volume of the measure reach a minimum fill volume height. This minimum height is dependent on the probe model and the assay container model. When measuring conductance of low volume samples, the best containers to use are Model[Container, Vessel, "id:4pO6dM5WvJKM"], which requires 475uL of sample, or Model[Container, Vessel, "id:o1k9jAG00e3N"], which required 675uL of sample.
