Universal Sample
Chamber
Our universal sample chamber can be
configured for transmittance, reflectance, absorbance,
or fluorescence measurements, with 0° or 45° sample
positioning depending on the type of measurements required.
It accepts standard 1-cm square cells or solid samples
up to 50 x 50 x 10 mm, with custom sample holders available
upon request. The sample chamber is normally set up
with a scanning monochromator, which delivers monochromatic
light. A quartz lens focuses this incident light in
the center of the cell, or at the front surface of a
sample depending on the position of the sample stage.
Another quartz lens focuses the reflected, emitted,
or transmitted light to the in-line port, or 90° exit
port. A suitable detection system is then used to collect
the light for analysis. As this is a singlebeam sample
chamber, it requires a scan of the incident light with
no sample, and then a second scan with the sample in
the beam. The two scans are then ratioed to yield the
sample characteristics.

Model SC-447
is a four-port sample chamber with rotatable platform
for holders (see below), a mount for slit assemblies,
two ports compatible with light sources or detectors,
one aperture port for customer-supplied accessories
or beam dump, and two quartz lenses. It requires a sample
holder for operation.

Model
447-1
is a general-purpose
sample holder that includes a holder for standard 10-mm-path-length
cuvettes and a spring-clip-style holder for samples
up to 50 x 50 x 10 mm. |

Model 447-2
is a fixed-position mount with a removable sample holder
for 1-inch-diameter samples. The removable sample holder
slides into a fixed-position mount. It allows measurements
at 0° and 45° with the beam passing through the center
of the sample.

|
Model 447-3
is a fixed-position microscope slide holder that is
designed to hold standard 1 x 3-inch slides. Stepped
guides with spring clips hold the long edge of the slide
so that the center of the slide (or sample) does not
contact the holder. It allows 0° and 45° testing.
