Bag In/Bag Out (BIBO) is commonly used in fields such as chemical analysis and environmental monitoring, primarily for automated extraction and analysis of gas samples. The correctness of its use and maintenance is crucial to ensure the long-term stable operation of the equipment and reduce errors. The following are the key points for the use and maintenance of the airbag automatic sampler:
1、 Instructions for use
Installation and Configuration
Ensure that the equipment is installed in a well ventilated area, avoiding environments with high temperatures, humidity, or corrosive gases.
When installing the airbag, ensure that the airbag opening is sealed to avoid external gas contamination of the sample.
Configure a suitable gas sample inlet pipeline and connect it to the analysis equipment.
Pre startup inspection
Check the parameter settings of the sampler to ensure that the sampling time and sample size of the equipment meet the experimental requirements.
Ensure that the airbag is not damaged or leaking, and use a pollution-free airbag.
Verify the pressure and flow sensors of the equipment to ensure accurate data.
Sample collection
Activate the airbag automatic sampler, and the equipment will automatically extract gas samples into the airbag.
Pay attention to the sampling time and frequency, and set the automatic operation mode of the sampler according to the experimental requirements.
sample analysis
The samples inside the airbag can be analyzed using analytical equipment such as gas chromatography and mass spectrometry to ensure the sealing of the samples before analysis.
2、 Maintenance and upkeep
regular cleaning
After each use, the sampling pipeline and airbag interface of the sampler should be cleaned in a timely manner to prevent sample residue from affecting the next sampling.
Use dust-free tissues or professional cleaning equipment to avoid direct contact with the inside of the equipment by hand.
Check the airbag
Regularly check the integrity of the airbag to ensure there is no wear or damage.
If the airbag is used multiple times, it is recommended to replace it regularly to avoid sample contamination caused by airbag damage.
Replace consumables
Regularly inspect and replace consumables such as filters, seals, etc. to avoid gas leaks or inaccurate sampling caused by damage to these components.
Check the sealing performance of the airbag interface to ensure there is no leakage.
periodic calibration
Regularly calibrate equipment, especially pressure sensors and flow sensors, to ensure their optimal working condition.
It is recommended to use standard gases for calibration to ensure measurement accuracy.
store
When not in use for a long time, the equipment should be emptied of sample bags, cleaned, and stored.
The storage environment should avoid places with high temperature and humidity to prevent damage to equipment and accessories.
troubleshooting
If encountering abnormal equipment operation, the first thing to check is whether the pipeline is blocked, whether the airbag is damaged, and whether the interface is sealed.
If the malfunction cannot be resolved, promptly contact the manufacturer for technical support and repair.
Through standardized use and regular maintenance, the airbag automatic sampler can operate stably, improving the efficiency and accuracy of sample collection and analysis.
