Grating

The FS500 full-spectrum direct-reading spectrometer uses a 500mm focal length grating, which achieves good resolution and improves testing accuracy and repeatability. With a large focal length and good resolution, it effectively reduces spectral interference and optimizes the selection of spectral lines, allowing for the use of more high-performance spectral lines.

Detector

The FS500 full-spectrum direct-reading spectrometer adopts new CCD detector technology and is equipped with a detector design with the highest number of pixels and the largest pixel height in the industry - 3648 pixels and 200 μm pixel height.

Up to 16 CCD detectors according to application needs, increasing the flexibility of instrument matrix and elemental analysis upgrades;higher pixel design achieves better spectral resolution,larger pixel height results in better detection intensity.

Vacuum light chamber

The FS500 full spectrum direct-reading spectrometer adopts a vacuum-type optical chamber and is equipped with an advanced intermittent vacuum system. The optical devices are sealed in a vacuum environment to extend the lifespan of the optical devices.

The precision processing technology ensures excellent sealing performance of the chamber, and it is equipped with ultra-high vacuum precision valves. The working time of the vacuum pump is less than 10 minutes per day. It retains all the advantages of traditional vacuum design while completely avoiding its energy consumption and slight oil pollution disadvantages.

Compared with argon gas flushing chamber:

Firstly, both designs can meet the basic testing needs of ordinary users.

The vacuum chamber design is a high-end instrument configuration that guarantees high performance. Manufacturers need to configure vacuum pumps and accessories, which increases costs but provides better performance.

Argon gas flushing design is a cost-saving measure by manufacturers, who reduce the cost of the vacuum system at the expense of some performance, thereby increasing user costs. Users consume more argon gas and periodically replace expensive consumables (purification tubes).

1. Resolution

The larger focal length in the vacuum chamber results in better resolution.

In order to reduce space for argon gas flushing, the focal length in argon gas flushing chambers is generally less than 200mm, resulting in poorer resolution.

2. Spectral transmittance

Vacuum ultraviolet spectral lines (involving typical elements such as C, P, S, B) have better transmittance in a vacuum environment.

3. Chamber cleanliness

Advanced intermittent vacuum systems are used to ensure complete cleanliness and no contamination inside the chamber.

Argon gas flushing chambers may introduce moisture and particles along with argon gas, contaminating fragile gratings and CCDs.

4. Operating costs

By using an advanced intermittent vacuum system, only ten minutes of operation from the vacuum pump are required each day with minimal electricity consumption.

Argon gas flushing chambers consume a large amount of argon gas, and the periodic replacement of consumables (purification tubes) is costly.

Excitation platform

The spark stage of the FS500 spectrometer adopts a sealed design. The structure of the entire spark stage is solid, maintaining the stability of the spark stage structure when the instrument continues to use high-temperature spark excitation.

The spark stage of the FS500 spectrometer improves the injection direction of the argon gas flow through structural design changes, which greatly reduces the residue of spark excitation residue on the spark stage, and also makes the cleaning and maintenance of the spark stage easier.

The FS500 spectrometer retains the design of an open sample stage, making sample placement and analysis easier, and sample processing is simpler than traditional spectroscopy. There are no special adjustment requirements except the electrode gap.

Electrical system

The circuit system of the FS500 spectrometer has been redesigned. The latest technology is used in both the spark source and readout system.

The FS500 spectrometer adopts synchronous real-time digital readout technology, which greatly improves analysis time and data stability compared to traditional sequential readout technology.

The FS500 spectrometer uses fully digital plasma spark source technology. All excitation parameters can be customized by users through the user interface according to actual needs.

The circuit system of the FS500 spectrometer is completely separated from the optical system, with the circuit system placed outside the instrument's optical chamber. This design greatly enhances the instrument's heat dissipation function and makes subsequent maintenance very convenient.

Self-calibration function

During each excitation, the optical system automatically scans the spectral lines to ensure the accuracy of reception and eliminate the tedious work of peak scanning.

Full-spectrum technology automatically traces and adjusts the optical path. When the sample is excited, the instrument automatically identifies the specific spectral line on each CCD, compares it with the original stored line, 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. Full-spectrum technology automatically and quickly addresses, avoiding laborious manual operations and avoiding human errors.

Later expansion

The FS500 full spectrum direct-reading spectrometer is based on CCD full spectrum testing technology, which can comprehensively test the types of intermediate elements in various metal materials. The instrument can conveniently add spectral lines and increase the matrix without adding hardware facilities, thus realizing multi-matrix analysis.

Customers can add matrices and types of elements to be analyzed on the instrument according to their actual needs during use. These tasks can be easily completed at the user's site.

Easy to operate

The FS500 full-spectrum direct-reading spectrometer analysis software has a good user experience and is easy to learn. After simple training, operators without professional background can use the software to perform sample testing and instrument calibration.

At the same time, the design of the FS500 full-spectrum direct-reading spectrometer reflects a people-oriented design concept, making the use and maintenance of the instrument reflect humanized care in every aspect.
