Validation Using Filters
Absorbance accuracy is most conveniently measured using certified
filter sets calibrated by Cecil Instruments against NPL certified
standards. A validation printout for the procedure is shown here.
Wavelength calibration is also carried out using certified filters.
Cell and Wavelength Programming
All Aquarius instruments are fully programmable. Cell programmes
may use four, six or eight cell changers, with a single autozero
or individual zeros for each cell.
Wavelength programmes are provided for up to ten different wavelengths
and cell and wavelength programmes may be combined.
Sampling/Temperature Control
A complete range of sampling accessories is available. A selection
of auto-sample changers, some with water temperature control, is
shown on the left. A thermoelectric controller with a single cell
holder and four cell changer is shown above. Control is through
the instrument microprocessor system with screen display of temperature. |
