Infrared spectrophotometer

1. Product Introduction:

The HD-HC500 infrared spectrophotometer is developed and manufactured according to the Chinese environmental protection standards "HJ637-2018 Determination of petroleum and animal and vegetable oils in water quality by infrared spectrophotometry", "HJ1051-2019 Determination of petroleum in soil by infrared spectrophotometry", and "HJ1077-2019 Determination of waste gas, oil fume and oil mist from fixed pollution sources by infrared spectrophotometry". The instrument is mainly used to detect the oil content in surface water, groundwater, industrial wastewater, soil, waste gas, oil fume and oil mist from fixed pollution sources. Special infrared spectroscopy analysis instrument.

2. Application scope:

The infrared spectrophotometer can be widely used in water environment detection systems, sewage treatment plants, water companies, petrochemicals, university research institutes, hydrology and water conservancy, metallurgy and steel, biomedicine, agricultural environment monitoring, wool textile printing and dyeing, marine environment monitoring, papermaking, medicine, agricultural technology, marine transportation and other fields.

3. Product Principle:

HD-HC500 infrared spectrophotometer extracts oil substances in water with tetrachloroethylene according to HJ637-2018 standard, determines the total extract, and then adsorbs the extract with magnesium silicate. After removing animal and vegetable oils and other substances, the petroleum is determined. The content of total extract and petroleum are calculated by the absorbance A2930, A2960 and A3030 at the wavenumbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-H bond in CH3 group) and 3030cm-1 (stretching vibration of C-H bond in aromatic hydrocarbons). The content of animal and vegetable oil is calculated as the difference between the total extract and the petroleum content.

4. Product Features:

1. It meets the standard HJ637-2018, the infrared three-wavenumber spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by the three wavenumbers can be clearly displayed;

2. The instrument adopts the Android 7.1 version intelligent operating system, built-in Holder Electronics special oil tester analysis software, integrating spectrum, scanning, analysis and calculation;

3. The instrument has a built-in 8-inch high-definition color touch screen, which can be operated by touch screen and external wireless mouse and keyboard, which is convenient and fast;

4. The instrument has both correction coefficient calibration and standard curve calibration. Multiple calibration methods meet the detection requirements of different use environments, and users can also establish standard curves by themselves;

5. The service life of the light source can reach more than 10,000 hours. The light source uses electrical modulation and light source technology to prevent the internal temperature of the instrument from being too high and affecting stability;

6. The detachable integrated optical system makes the instrument small in size, short in optical path, large in energy, and the optical path meets the requirements of infrared spectrum characteristics, with good stability and high signal-to-noise ratio;

7. It not only has basic functions such as detection function setting, curve analysis, historical data, etc., but also can zoom in and out the spectrum, allowing users to infinitely refine the spectrum and observe the curve at low concentration more clearly;

8. Automatically synchronize network time to avoid the accuracy of output voucher time caused by inaccurate local time after using the instrument for too long;

9. The weak signal conditioning circuit developed independently is adopted to effectively shield noise interference and greatly improve the detection accuracy and detection limit;

10. Highly automated program application, users can use the Android system to perform single-step tests of all functions of the instrument, automatic wavelength scanning, automatic correction and other functions, making data detection more accurate;

11. The instrument has the function of detecting the purity of the extractant to effectively avoid detection data errors caused by the purity of the extractant not meeting the standard;

12. Support wifi and Bluetooth transmission, and data can be uploaded to the cloud data management platform wirelessly; support USB flash drive copying data, free of drive plug-in;

13. Configure the Holder Electronics Cloud Data Management Platform, the test results can be permanently stored, and long-term and short-term viewing and analysis can be performed to assist management;

14. One-click program upgrade function, no need for engineers to download on site, the APP can be upgraded by inserting a USB flash drive;

15. The use of electrically modulated light source not only reduces the heat intensity of the light source to facilitate system heat dissipation, but also simplifies the instrument structure and improves the reliability of the instrument by reducing the mechanical light cutting motion devices;

16. Real-time automatic zeroing, the instrument collects signals when the light source is on and when the light source is off, realizing real-time automatic adjustment of the zero point, thereby simplifying the operation and improving the long-term stability of the signal;

17. High measurement accuracy, using a high-precision 24-bit AD detection chip for analog-to-digital conversion, can accurately measure small signals at the uV level;
