VL-4000 direct reading spectrometer

1、 The VL-4000 direct reading spectrometer, with its high performance and reliable design, can ensure accurate identification and trace analysis of important elements. The instrument has a low detection limit and excellent long-term stability; The analysis results are accurate and have good reproducibility. The combination of detectors and digital readout technology in Chuangxiang Instrument has made the overall design of the instrument superior to traditional photomultiplier tube technology, and has gradually become an important choice for metal manufacturing, processing, and casting industries.

2、 The VL-4000 direct reading spectrometer adopts a brand new optical system design, which combines optimized pixel resolution measurement technology and grating spectroscopy technology, representing the direct reading spectroscopy technology of the digital age. Each element is analyzed using multiple spectral lines for comprehensive output, with a large dynamic range and accurate results. The placed detector meets the requirement of receiving all spectral lines within the analysis band without any omission, achieving simultaneous measurement of multiple spectral lines of the same element, automatically selecting output, and aiming at the observation characteristics of plasma state spectral signals, in order to obtain good observation angles and analysis data.

3、 The VL-4000 spectrometer automatically scans spectral lines with its optical system during each excitation, ensuring accurate reception and eliminating the tedious task of peak scanning. The full spectrum technology automatically traces and adjusts the optical path. When exciting the sample, the instrument automatically recognizes specific spectral lines on each detector, compares them with the original storage lines, determines the drift position, and finds the current pixel position of the analysis line for measurement. Eliminate spectral drift caused by changes in temperature, air pressure, vibration, etc; The traditional use of photomultiplier tube technology requires manual fine adjustment of spectra, which has high technical requirements. Full spectrum technology automatically and quickly addresses, avoiding laborious manual operations and human errors.

4、 The VL-4000 spectrometer adopts full spectrum direct reading technology, which makes it very convenient to add spectral lines and substrates. It can achieve multi substrate analysis without adding hardware facilities. Customers can add analysis matrices and element types to the instrument according to their actual needs during use, and these tasks can be easily completed on the user's site. Compared to similar spectrometers that use PMT technology, it requires extensive hardware modifications. Due to the configuration limitations of the initial instrument, it may not be possible to add the matrix or elements requested by the customer.

5、 The spark table of VL-4000 spectrometer has been redesigned, retaining the advantages of traditional spark tables while optimizing for new application requirements. The spark table adopts a sealed design, and the entire structure of the spark table is sturdy, maintaining the stability of the spark table structure under the continuous use of high-temperature spark excitation by the instrument.

6、 The spark table of VL-4000 spectrometer has improved the direction of argon gas flow injection through structural design changes, greatly reducing the residual spark excitation on the spark table and making cleaning and maintenance of the spark table easier. The VL-4000 spectrometer retains the design of an open sample stage, making sample placement and analysis easier, and sample processing simpler than traditional spectroscopy. There are no special adjustment requirements except for the electrode gap.

7、 The VL-4000 spectrometer adopts a unique jet electrode technology (JET Stream). In the excited state, an argon gas jet will form around the electrode. This technology will bring the following advantages: the argon gas flow around the excitation point ensures that the excitation process is not affected by external interference. Saved the use of argon gas and reduced the customer's operating costs. The sample stage does not require sealing, and small samples such as wires can be easily analyzed with the help of adapters. Pull out front cover makes cleaning and maintenance of the excitation table more convenient.

8、 The incident light path design of VL-4000 spectrometer is simple. By directly connecting the incident light path to the light chamber system, the two lens incident windows ensure that dust and protection are separated independently, making maintenance and cleaning very convenient. Customers can operate on their own in daily work; The circuit system of VL-4000 spectrometer has been completely redesigned. The spectrometer adopts synchronous real-time digital readout technology, which greatly improves the analysis time and data stability compared to traditional sequential readout technology.

9、 The VL-4000 spectrometer adopts fully digital plasma spark light source technology. All excitation parameters can be customized by users through the user interface according to their actual needs. The VL-4000 spectrometer completely separates the circuit system from the optical system, placing the circuit system uniformly outside the instrument's light chamber. This design greatly improves the instrument's heat dissipation function and makes subsequent maintenance of the instrument very convenient.

10、 The operating software of VL-4000 spectrometer is very simple and easy to learn, with full Chinese or English menus. Operators without any background in spectral instrument knowledge only need simple training to operate the instrument.
