VOC online monitoring gas chromatograph
VOC online monitoring gas chromatographProduct Introduction:
The system adopts a dedicated chromatographic column combination, center cutting and blowback technology, and hydrogen flame ionization detector（FID technology is used for detection. After the sample is collected into the quantitative loop, it is driven by the carrier gas to switch the injection valve and enter the chromatographic column for separation. After that, it enters the FID detector to detect the results.

VOC online monitoring gas chromatographcharacteristic:
Using center cutting and back blowing technology, in accordance with the standard HJ/T38-1999, direct sample measurement is carried out.
Using a dedicated chromatographic column combination, the sample peaks within 30 seconds at 180 ℃ without residue and has high sensitivity;
●instrumentEquipped with power on self-test function, power-off protection function, automatic restart function and alarm function, ensuring system safety and stability;
The FID detector has automatic ignition function and wide range output, with a linear range of 10-7;
Using high-precision control valves, carrier gas, air, and hydrogen can achieve high repeatability and stability;
The core components are all made of internationally renowned brands, with high reliability and long service life.
VOC online monitoring gas chromatographApplication areas:
1. Environmental air online monitoring or scientific research
2. Online monitoring of discharge outlets or factory boundaries for petrochemical, spraying, printing, etc
VOC online monitoring gas chromatograph technical parameters:
| TECHNICAL INDEX | |
| detectability | Methane, non methane total hydrocarbons, total hydrocarbons |
| Range | Methane (0.1-10000) ppm; Non methane total hydrocarbons (0.05-10000) ppm (optional) |
| detector | Hydrogen flame ionization detector (FID) |
| detection limit | ≤ 0.1ppm (methane), 0.05 (non methane total hydrocarbons) |
| repeatability | RSD≤2% |
| Analysis cycle | Single channel ≤ 40S; Dual channel ≤ 20S |
| Power supply | ＜300W，220V AC/50HZ |
| work environment | Temperature: (-10-50) ℃, humidity (10% -100%) |
| Air source requirements | Carrier gas: high-purity nitrogen or zero grade air (≥ 99.999%) |
| combustion gas | High purity hydrogen gas (≥ 99.999%), auxiliary gas: zero grade air (hydrocarbons<20ppb) |
| Sample flow rate | 10-500ml/min |
| Data storage format | The data is saved on the hard drive of the industrial control computer, and will not be lost when the power is turned off, making it easy to trace the data |
| Multi channel switching function | Can detect 16 channels of VOCs samples that are not connected (optional). It is recommended not to use this online. Multi channel switching is solved by an integrated commercial solenoid valve, which has a high failure rate in this area. |
