Infrared spectrophotometer

1、 Product Introduction

1MX-100 modelInfrared spectrophotometerIt is not only suitable for monitoring the content of petroleum (mineral oil), animal and vegetable oils, and total oil in various water bodies and soils such as surface water, groundwater, seawater, domestic water, and industrial wastewater, but also recommended by the national standard for monitoring the oil content of flue gas (cooking fume) in the catering industry. In addition, it can also be used for purity detection of organic reagents and measurement of the total amount and amount of organic compounds containing various C-H bonds.

2. Compliant with the standard: National Environmental Protection Standard of the People's Republic of China "HJ637-2018" Determination of Water Quality, Petroleum and Animal and Vegetable Oils by Infrared Spectroscopy "

3. The MX-100 infrared spectrophotometer uses infrared spectrophotometry for measurement. After scanning the sample spectrum, it can display and print the sample spectrum and the wavenumber position of the absorption peak. It can quickly and accurately measure the total content of oil concentration in water.

2、 Product parameters

1. Method detection limit: When the sample volume is 500ml and the extraction solution volume is 50ml, the detection limit is 0.06mg/L;

3. Wave number accuracy and repeatability: ± 0.5cm-1. Using automatic positioning calibration, oil samples above 30mg/L are automatically calibrated at 2930cm-1, 2960cm-1, and 3030cm-1, eliminating the influence of human positioning;

4. Repeatability: RSD ≤ 0.6% for 11 measurements of 30-40mg/L oil standard samples. The instrument's optical and electrical systems are self-contained and highly integrated, thereby improving the reliability and repeatability of the instrument;

5. Accuracy error: ≤ 1%;

6. Correction coefficient accuracy: Take an appropriate amount of petroleum standard solution, prepare an appropriate concentration of petroleum standard solution using tetrachloroethylene as the solvent, and measure it using the same steps as the sample, with an error of ± 10%;

7. Scanning speed: Full spectrum scanning, 30 seconds/time; Non dispersive infrared method 2 seconds/time;

8. Basic measurement range: 0.0~800mg/L;

9. Low detectable concentration: 0.003mg/L (water sample concentration);

10. Maximum measured concentration: 100% oil;

11. The linear correlation coefficient r is greater than 0.999;

12. Wave number range: 3400cm-1 to 2400cm-1 (i.e. 2941nm to 4167nm);

13. Absorption range: 0.0000-2.0000 AU (i.e. transmittance of 100-1% T);

14. Temperature: -5-45 ℃;

15. Relative humidity: 5% -95%;

16. Host power supply: (220 ± 22) V, (50 ± 1) Hz, 50VA;

17. Shell material: integral engineering plastic structure (PC+ABS), anti electromagnetic radiation treatment, impact resistance, anti-corrosion;

18. Host dimensions: 550mm (length) x 430mm (width) x 160mm (height);

19. Host weight: 14kg (appearance and weight subject to actual).

3、 Configuration requirements

1. Large screen touch screen design, no need for an external computer, the system realizes touch control compatible with wireless keyboard and mouse control;

2MX-100 modelInfrared spectrophotometerEquipped with self checking and result judgment functions: it prompts for abnormal energy and possible causes for troubleshooting reference. It also has the function of generating instrument self checking energy information logs and software judgment to indicate whether the sample exceeds the standard;

3. Communication method: Bluetooth USB、 Serial port;

4. Cloud database: The instrument is equipped with a set of cloud databases, which store the self checking status information of the instrument and the content of each test (operator, time, test results, sample name, etc.);

5. The instrument uploads cloud data using GPRS, NB-IOT, WIFI;

6. Baseline stability: Real time automatic adjustment of zero point (eliminating the influence of baseline drift), the computer collects both the signal when the light source emits light and the signal when the light source goes off, achieving real-time automatic adjustment of zero point, simplifying operation and improving long-term signal stability;

7. Dual national standard software system: using dual system analysis to meet the usage of carbon tetrachloride or tetrachloroethylene as extractants respectively;

8. Calibration method: The instrument can be calibrated using both standard curves and coefficients, with multiple calibration methods to meet different environmental requirements;

9. Light source system: The service life of the light source can reach over 5000 hours. The light source uses electrical modulation to regulate the light source technology, preventing the internal temperature of the instrument from affecting stability;

10. New layout of electronic components, electromagnetic compatibility, better stability, and structurally more suitable for upgrading.
