The QTSN-3000 sulfur and nitrogen analyzer is currently a relatively advanced integrated sulfur and nitrogen analyzer. Detection methods: UV fluorescence method to determine sulfur content, chemiluminescence method to determine nitrogen content. The instrument has stable and reliable performance, high analysis accuracy, good repeatability, convenient and flexible operation, and can replace imports. JQTS-3000 modelUV fluorescence sulfur analyzer、 The JQTN-3000 nitrogen content analyzer is a type of single element analyzer that can be quickly upgraded to the JQTSN-3000 sulfur and nitrogen analyzer by adding corresponding detection modules. Our company's researchers are developing new product upgrades for vertical automatic sampling, cleaning, automatic fitting of standard curves, automatic calibration, and automatic detection of multiple samples
Main features:
☆ High sensitivity: Advanced analysis methods are adopted, and imported components are used for key components, ensuring reliable performance of the entire machine.
Good repeatability: Once the working curve is calibrated, it can be used for a long time, reducing accidental errors caused by different calibration habits of operators.
☆ Safety and environmental protection: It does not use various chemical reagents required for wet chemical methods, greatly reducing the workload of operators. Staff do not need to come into contact with chemical reagents, and the entire testing process does not produce toxic substances.
☆ Easy to operate: Based on the Chinese operating interface of Windows, the operation is more convenient and fast. All parameter settings, condition selection, data acquisition, processing, storage, and printing are controlled by a computer.
☆ Complete configuration: host, temperature control system, computer, printer, automatic liquid sampler.
Other optional components: solid sampler, gas sampler.
