X-ray Fluorescence spectrometer

Main features:

• Simultaneous analysis of many elements (From Na to U, any number of elements).
• Design used on the photo; completely avoid contamination, ease of operation, no maintenance.
• Non-destructive analysis of samples, analysis convenient.
• Automatic mechanical and electrical integration design, simple interface.
• Eight-sample auto sampler and sample auto-detection. Fully shielded X-ray multi-layer protection of the radiation on the human body.
• Good temperature control equipment, apparatus, to the outside world is not sensitive to temperature changes.
• Requires less sample forms, solid, liquid, powder samples can be directly detected, without complicated sample preparation process.
• SDD detector, fast, high accuracy, good stability, low failure rate.

Main technical

1.Detector

a)         Silicon drift detector SDD (Electric refrigeration, only by power).

b)        Typical resolution :123ev, 133ev (50000CPS)

c)         Input count rate : 100KCPS , Much larger than the Si-Pin and Si-Li (About its 10 times).

d)        Peak to background : >20000

e)         Beryllium window thickness:8um Dura Be (General probe 25um, for better transmission of light elements, unique Dura Technology Be windows to acid and alkali corrosion)

f)         Processor: Digital circuits, magnification, time constant can be set.

g)        High Life, Dura Be with its unique technology, the vacuum of the detector probe in a few years’ time will not go; also the crystal will not be damaged without worrying                  about the later maintenance costs.

2.    X-ray tube

1)        High voltage: Continuously adjustable 0-50Kv

2)        Current: Continuously adjustable 0-1000uA (0-2500uA optional, High current effect on better excitation of Na-K better)

3)        Power: 50W

4)        Stability: 8 hours 0.2%

5)        High life, the correct operating conditions can reach 50,000 hours life.

3.   High voltage generator

a)         Input Voltage :24VDC /Input current :4A

b)        Output Voltage :50Kv ,1mA (2.5mA Optional, Light pipe adapter 2500mA)

c)         Maximum power:50W /Stability: 8 hours 0.05%

4.   Precision of structure design

Design of vertical chamfer, Sophisticated control to ensure excellent repeatability, design on the photo can completely avoid the dust pollution to ensure that the instrument can be truly maintenance-free.

5.   Cooling system

Good multi-stage temperature control since the feedback circuit , Room temperature is 5-25 ℃, Results will not affect the instrument.

6.   Automatic Sampling System

--8-sample auto sampler
