Atlantis PMT/CCD direct reading spectrometer

1、 Instrument Introduction

Atlantis is the culmination of GNR's 25 year direct reading spectrometer manufacturing technology, with analytical capabilities.

The quality manufacturing process enables Atlantis to meet various analytical requirements, suitable for: production process analysis and control; Quality Control; The special and complex applications of the R&D department.

Atlantis can be equipped with an MDS system, which combines PMT and CCD technologies to provide users with precision, flexible element range selection, and multi substrate applications. This instrument can quickly and accurately analyze the main alloying elements as well as trace elements. Examples include O, N, P, B... in steel, copper alloys, aluminum alloys, titanium alloys, and so on.

The precision and analytical quality achieved by using international standard samples to create working curves in manufacturers. If there are more complex and specialized applications, our experts can provide you with new analysis methods and solutions.

The optical chamber made of aluminum alloy is sturdy and reliable, with optimized Paschen Runge structure and high stability temperature and pressure control, which can make the system relatively isolated from external environmental conditions.

The readout system can simultaneously receive signals from photomultiplier tubes (PMT) and CCD detectors. All data display, analysis and processing are completed in one full band scan.

The variable frequency spark source controlled by PC can improve the accuracy of plasma, while also increasing repeatability and reducing detection time.

The analysis software is easy to operate, efficient and fast in daily analysis, and automatically standardized to support remote control through network connection.

The instrument has self diagnostic function and can automatically monitor the working status of the instrument.
