HTO Bubbler
Model RPB100 |
The
RPB100 Portable HTO Bubbler is a two-vial,
single stage bubbler designed for emergency
response and short-term sampling applications.
It is a complete HTO collection system
contained in its own custom carrying case.
Sample
gas enters the instrument through a quick-connect
gas inlet fitted with either a gas sampling
funnel for local sampling or hose for
remote sampling. The sample gas flows
through two 500 ml standard vials of
ethylene glycol which retain the HTO
component. The sample gas, now less the
tritiated water vapor, flows through
a mass flow meter and user adjustable
regulating valve to adjust sample flow.
A vane pump pulls the sample gas through
the system and exhausts it from the case.
A VFD displays the flow rate, elapsed
time, and totalized flow. The user can
reset the elapsed time and totalized
flow. After power (120VAC) interruption,
the system recovers the elapsed time
and totalized flow from EEPROM and continues
operation.
| Dimensions: |
21.0
W X 17.0" H X 7.5"D (54cm X 43cm
X 19cm) |
| Weight: |
22 lbs (10
kg) |
| Flow
measurement: |
Electronic
mass flow meter (1-5 liters/min, 0.05 liter/min
resolution). Flow is user controlled via
manual 8 turn metering valve. Instantaneous
and totalized flow are displayed on LCD. |
| Sensitivity: |
Detection
limit of HTO in ambient air is at least
1E-10 µCi/cc |
| System protection: |
In-line filter
to protect flow controller and pump; vacuum
gauge to monitor pump performance. |
| Operating
parameters: |
5
to 40°C
and 0 to 95% rh non-condensing. |
| Sample
Inlet |
Quick
disconnect receptacle accepts mate with ¼" Swagelok® fitting
for various accessory sampling devices |
| Bubbler
Vials |
One
stainless steel two-vial bubbler assembly
is connected
with Swagelok® bulkhead fittings.
This design permits removal of the vial
assembly for easy cleaning with water
and ethanol if necessary. The bubbler
assembly collects HTO. Vial caps are
threaded and fitted with 0-rings in order
to provide a quick and reliable seal
with the 500 ml polyethylene vials. Special
machining of the cap thread allows the
use of vials from any vial manufacturer. |

Vacuum fluorescent
display provides: |
| FLOW

Instantaneous flow
rate in liters per minute |

| Display
Refresh |
As
a vacuum fluorescent display can "burn in" a
repeated image, the display will automatically
go blank after a preset time in order
to protect the display. This momentary
push button will reactivate the screen
should it be blank. |
| Totalizer
Reset |
Key switch
that resets the elapsed time and total
flow to zero values to begin sample period.
Unit can only be reset without key. |
| Flow
Adjust |
This 8 turn
metering valve controls the system flow
rate from approximately 0.5 l/min to
4.5 l/min. |
| Vacuum
Gauge |
The
pump performance can be monitored by
this
0-30" vacuum gage. |
| Power
Switch |
Controls
AC power to the RPB100, "1" is
ON, "0" is OFF |
| Fan |
The
fan is activated when the "POWER" switch
is ON. |
