Introduction
• Argon fulfillment optical chamber occupies smaller space with less energy consumption.
• Czerny-Turner optical system is applied for a better plane CCD collection for all elemental wavelength that falls into 140-750nm.
• Self-developed DF-IV collection device for spectral lines is available for wavelength range between 140nm and 750nm.
• Several matrices can be analyzed such as Fe, Cu, Al, etc.
• Module design for independent light collection, data processing and data optimization. With the help of high-performance ARM processor and real-time operational system, analytical time is largely shortened and accuracy is further improved.
• 3G thermostatic system improves the energy efficiency to a great extent. The temperature fluctuation range of ±0.2℃ makes the DF-400 perform more stable.
• The DF II-S digital-controlled light source increases the elemental analytical range and accuracy.
• Plane grating allows smaller number of CCD, further improving the accuracy and stability. It also occupies smaller space and makes set-up and movement a lot easier.
• The multipurpose operational software can meet various needs by displaying elemental data in a flexible way and supporting various printing formats.
