順序波長色散X射線光譜儀WDX-4000主要特點(diǎn)：
的測角儀的設(shè)計(jì)
●創(chuàng)新和火成鋼皮帶傳動系統(tǒng)。這種的設(shè)計(jì)提供了無摩擦，沒有反彈，穩(wěn)定的運(yùn)動，保證確的角度定位。
●8/28軸有獨(dú)立的驅(qū)動系統(tǒng)和伺服電機(jī)編碼器反饋
●永磁同步電機(jī)（PMSM）提供、最平穩(wěn)的運(yùn)動
●光學(xué)編碼器0.0001°分辨率和0.0006°精度保證集成系統(tǒng)達(dá)到優(yōu)良的性能。
多通道分析儀
●12位，80msps，大的AD采樣系統(tǒng)、完整、準(zhǔn)確地記錄信號
●4096（12bit）通道分析儀基于高速FPGA架構(gòu)和強(qiáng)大的DSP算法能夠區(qū)分正確的X射線從噪聲和雜散光
●能量色散作用是額外的。
ray Tube高壓發(fā)生器
●標(biāo)準(zhǔn)功率kw系統(tǒng)給出了痕量元素的分析靈敏度和較高速度的分析
●薄鈹窗（50um或75um）提供了X射線超傳輸，特別是低能量區(qū)
●60kV及140ma，（75kv 150mA是可選的）和靈活的設(shè)置有助于更精細(xì)的分析方法
●雙循環(huán)水冷卻系統(tǒng)，去離子水的電導(dǎo)率保持比1us由管壽命的樹脂增加盡可能低的多。
