| Model 905V |
| The Model 905V measures oxygen
levels |
| PHARMACEUTICAL APPLICATIONS |
Pharmaceutical preparations packaged
in vials are often gas-flushed to provide a specific atmosphere in the
vial, with defined levels of oxygen, nitrogen or other gases. Depending
on the product, these vials can range in size from 1 ml to 250 ml or larger.
Small vials present some difficulty for oxygen analysis because the sample
volume available is often quite small. A one ml vial, for example, may
have only 0.5 ml of headspace gas. For direct analysis with an oxygen
analyzer, the instrument must be capable of analyzing very small volumes |
| LOW-VOLUME SENSOR DESIGN |
The Model 905V sensor is designed
specifically for this purpose. The oxygen sensor internal chamber has
a very small volume of about 0.1 cc. The sensor is located directly behind
the front panel to eliminate excessive volume. The sensor has in /out
ports with a 0.03 in. ID. The vent port of the sensor connects to a short
piece of narrow-bore tubing for sample exhaust and introduction of zero
or calibration gases. |
| CALIBRATION SIMPLICITY |
The oxygen sensor output is very linear
through the entire range of measurement. This allows for a single point
calibration to be performed anywhere in the measurement range. Span calibration
is accurately done by testing room air, which should give a reading of
20.9% oxygen. Calibration standards can also be used if required by in-house
test procedures. |
| LABORATORY OR PRODUCTION LINE |
The Model 905 is a rugged benchtop
unit housed in a heavy-duty metal enclosure, well suited for continuous
use in routine QC testing in the laboratory. With built-in battery operation
(optional) in addition to the AC mode, this unit can be easily transported
and used at remote locations such as the packaging line. |
| DESIGN RELIABILITY |
Microprocessor based electronics are
used for sensor signal processing, battery charging and on/off control
to provide high accuracy and reliability. The heavy duty, proprietary
oxygen sensor is designed to provide many years of service, is totally
sealed and requires no maintenance. The sensor output is compensated for
ambient temperature variations. |
