M400PC Accessories

Accessories available include:

• Long Pass Flowcell 1m - the concept of a 1M long pathlength allows measurements of extremely low concentrations of analytes. Developed principally for the water industry, this low volume (only 250uL sample volume) accessory can show up the differences in purity between for example distilled water and de-ionised water simply by measuring the absorbance difference at 250nm which is where most organic molecules absorb. The accessory consists of a 560micron (internal) diameter capillary tube that acts as both the sample holder and the wave guide for the light from the source. This arrangement is only available for fibre optics systems such as the M400. The sample is simply injected into the capillary using a syringe. It can also be pumped through the capillary.

• Diffuse Reflectance Probe for Measuring Coloured Samples - this probe can be used for measuring the colour of powders and thick fluids. The probe tip is dipped into the powder or liquid sample to measure the diffuse reflectance. This technique is used in quality control procedures for checking consistency of colour in the sample. The reflectance results are displayed as a graph and the data are processed to obtain the x and y co-ordinates for comparison purposes.
  The input fibre bundle consists of 6 fibres which are connected to the probe to illuminate the sample via a silica window set at 45 degrees. This angle is chosen to avoid collecting the specular, or directly reflected light from the window and the sample. A seventh fibre collects the diffusely reflected light from the sample.

• ATR Probe - for reducing the sensitivity compared with a 10mm dip probe (or 10mm cuvette) by x 10,000. This then allows absorbance measurements of undiluted samples. This is especially useful in the process environment.
