Automatic Air Sampling Pump
GSP-501FT
- Flow range 50-500mL/min
- 10-500mL/min is available when volume mode (When set to 10-49 mL/min, the intermittent operation is performed at 50mL/min)
- Fixed flow function automatically regulates load changes
- Flow rate, sampling time, and integrated volume are displayed on the same screen simultaneously
- Automatic start enables sampling to begin after a preset time
- 5 sampling settings can be saved with the program mode
- Real-time flow volume and integrated flow volume are automatically corrected to the values for 20ºC(68ºF) or 25ºC(77ºF)
OVERVIEW
Set two AA alkaline batteries or AA nickel-metal hydride batteries.
Specifications
Intermittent Operation
When the instantaneous flow rate is set to 10 – 49mL/min in the Volume Mode,the intermittent operation is performed by sampling at an instantaneous flow rate of 50mL/min.
Example of Intermittent Operation
When the Volume Mode is selected and the flow rate is set to 10 mL/min and the set volume is 0.1L, after the sampling is started, the pump will pause for about 48 seconds after about 12 seconds of sampling at a flow rate of 50mL/min (samples until the sampled volume per minute reaches 10mL, then pauses). A sampling at a flow rate of 50 mL/min for about 12 seconds and pausing for about 48 seconds are repeated until the set volume of 0.1 L is reached, taking about 10 minutes.
(Example) Volume Mode
- Flow rate: 10mL/min
- Integrated volume: 0.1L
Repeat until the sample volume reaches 0.1L
If there is a sudden change in the gas concentration or if sampling is performed for a short period of time, the error of the sampling result may be large.
Options
- Gas sampling pump tripod stand GSP-TRIPOD: Mount GSP-501FT to use at the desired height.
- Belt loop pump holder GSP500FT-30: Case for personal exposure measurement.
- Rubber caps DTP-2-20: Reusable rubber caps can be attached to the broken tip of the detector tubes as an extra precautionary safety measure. One (1) package contains 20 caps.
- Protective cover for detector tube GSP300-14: Enables the detector tube to be securely set up for measuring and helps to avoid possible injury to the user as well as damage to the detector tube itself.
- Sampling tube holder 730: Tube holder for personal exposure measurement.
- Tripod mounting plate PLATE 2: 2 pumps can be mounted on the same tripod.
Sorbent tubes
Sorbent tubes are glass tubes filled with sorption agents such as activated charcoal or silica-gel and are used to adsorb toxic gases in various environments. Both ends of the tube are broken off and connected to a sampling pump for sample collection. The adsorbate is then extracted using a solvent and analyzed using gas chromatography.
