Audited Supplier Introduction:
GD-4294 ASTM D4294 50 ppm Sulphur Content Analyser is specially designed to determine sulfur content in the petroleum products. Adopts energy-dispersive principle, and with electrical, mechanical and microprocessor integration design, so it is rapid and accurate. It can meet the requirements of National Standard GB/T 17040 and GB/T11140 on repeatability and reproducibility, and it can also meet requirements of ASTM D4294-03 on these indexes. It provides a measure to determine sulfur content during petroleum or petrochemical production process.
Specifications:
| No | Technical indicators | Technical parameter |

|
| 3 | Sample volume | 2 ~ 3ml (equivalent to sample depth of 3mm ~ 4mm) |
| 4 | Measurement time | 30, 60, 90, 120, 150 seconds, set arbitrarily |
| 5 | Measurement times | 1, 2, 3, 5, 10 arbitrary settings |
| 6 | Number of stored curves | 10 |
| 7 | Temperature | 5 ~ 35 ºC |
| 8 | Relative humidity | ≤ 85% (30 ºC) |
| 9 | Power supply | 220V, ACV ± 50Hz |
| 10 | Rated power | 30W |
a. Ambient temperature: 5~30ºC;
b. Relative humidity: ≤85% (30 ºC);
Advantages:
1. Runs on the windows operating platform, with man-machine dialogue and convenient operation.
2. No contact, no damage, no conversion, no high-temperature operation, no chemical reagent and no consumption of inert gas in sample analysis. High concentration samples do not need to be diluted, and the instrument can detect directly without causing any pollution to the instrument detection system.
3. Wide detection range: Determination of sulfur content in petroleum and various petroleum products.
Fast measurement speed: the sulfur content can be accurately measured in 1 ~ 5 minutes.
4. Special sample cup: the disposable special sample cup is adopted, which has low cost and can avoid cross contamination of samples; Sample making is fast and convenient, not easy to leak; The single facial mask sample cup is used, and the sample concentration, number, date, etc. can be recorded on the back of the sample cup.
6. Less consumption of standard samples: only 3 ~ 5 ml per time, which greatly reduces the consumption of standard samples.
7. Simple instrument calibration: put in the special standard sample for calibration, and the instrument can be calibrated quickly.
With automatic gain correction: when the X-ray tube is used for a long time and the energy decreases, the instrument will automatically adjust the corresponding algorithm to ensure the measurement accuracy, which actually prolongs the service life of the X-ray tube.
8. Automatic selection of standard curve: the instrument can store any number of standard curves, and the user can select the most suitable curve. If there is no selection, the instrument can automatically select a curve closest to the measured sample. If the measured sample exceeds the range of all curve measuring points, the instrument will use the "extrapolation method" to measure.
9. Pollution protection: the instrument is designed with LED optical total reflection imaging technology to check (judge) the overflow of liquid sample, which can avoid the leakage of sample box into the detection cabin and pollute and damage the instrument; Anti overflow is added in the instrument sample detection cabin
10. Protective device: prevent sample leakage during testing.
11. Safety protection: the instrument is equipped with strict X-ray leakage prevention measures and dust-proof and anti-corrosion devices.
