Peak Seek
The measurement of an absorption band should always be carried
out at the wavelength of peak absorption to obtain results of the
highest accuracy and reproducibility.
An automatic peak seek facility is provided. To enhance discrimination
and accuracy automatic compensation of the reference energy background
- baseline flattening - is carried out, followed by precise peak
location. The instrument is set to the peak wavelength, ready for
use.
Sample Temperature Control
Temperature control by water circulation is possible with the Series
1000 for a single cell, SIP flowcell, or for 4 cells mounted on
the cell changer. A special sample compartment lid and pipe port
are provided for use with water temperature control.
Convenient Sampling
The large and accessible sample compartment accommodates a wide
range of sample holders in addition to the standard single cell
holder. These include a 4 cell changer, water thermostatted cell
holders and a SIP sampling system which fits within the sample compartment.
SIP Flowcell Sampling
Used with Series 1000 instruments the SIP sampling accessory allows
samples to be measured without the inconvenience of cell handling,
or danger of cell breakage. Samples are drawn into the cell by depressing
the sample key on the control panel, to displace the previous sample.
The pump unit is mounted within the cell compartment. Cells of
up to 40mm pathlength are available and samples as small as 300µl
may be measured in a 10mm pathlength cell.
