產(chǎn)品簡介

憑借其采集速率達(dá)100平均譜圖/秒的能力，F(xiàn)ASTFLIGHT-2成為LC/TOF-MS/和GC/TOF-MS應(yīng)用中優(yōu)異的數(shù)據(jù)采集解決方案

詳細(xì)介紹

憑借其采集速率達(dá)100平均譜圖/秒的能力，F(xiàn)ASTFLIGHT-2成為LC/TOF-MS/和GC/TOF-MS應(yīng)用中優(yōu)異的數(shù)據(jù)采集解決方案。色譜技術(shù)正在向更短的保留時間發(fā)展，使得飛行時間質(zhì)譜（TOF-MS）獲取平均譜圖的速度越來越快。對比代的數(shù)字信號平均器，F(xiàn)ASTFLIGHT-2 將TOF譜圖處理速度提高了10倍，因而有能力適應(yīng)更快的色譜儀。

由于使用了采樣ADC以及硬件數(shù)字信號平均器，F(xiàn)ASTFLIGHT-2能處理LC/TOF-MS, GC/TOF-MS, Ion-Trap/TOF-MS 和 MALDI I TOF-MS中碰到的高速離子而不用像在時間數(shù)字轉(zhuǎn)換器（TDC）中遭受死區(qū)時間的困擾。對比瞬時數(shù)字轉(zhuǎn)換器以及數(shù)字采樣示波器，他們都面臨緩慢的軟件平均速度，F(xiàn)ASTFLIGHT-2傳遞平均譜圖的速度比它們快了好多個數(shù)量級。

其創(chuàng)新的，自動關(guān)聯(lián)噪聲消減特性意味著FASTFLIGHT-2在QqTOF-MS低速離子應(yīng)用中也是有效的解決方案，這一領(lǐng)域以前一直被認(rèn)為都是TDC和時間轉(zhuǎn)換器所。

Hardware	-
PERFORMANCE	-
Amplitude Digitizing Resolution	8 bit- ADC nominally spans 500 mV at the Analog Input.
Precision Enhancer	Extends the limiting ADC resolution to 12 bits (for input noise <2 mV) when circa 256 or more records are averaged^3.Optionally, on or off.
Differential and Integral Non-Linearity (DNL and INL)	Measured from 5% to 95% of full scale using a 500 mV, 70 µs ramp, with Precision Enhancer on. DNL within ±0.1 LDB referred to the 8-bit ADC. INL within ±0.4% of full scale.
Analog input Bandwidth	DC to 500 MHz; rise adn fall times <1 ns.
Equivalent input Noise	(Measured with 500 ps sampling and 50 µs record lenght.) Uncorrelated with the Trigger <2 mV rms. Correlated with the Trigger <0.02 mV (typically 0.01 mV rms) with Automatic Correlated Noise Substruction.
Automatic Correlated Noise Substruction	Automatically assesses the correlated noise in each spectrum and substracts it without compromising data throughout rates. Optionally, on or off.
Analog DC Offset (Vertical Offset)	Zero offset of the ADC is computer adjustable from -250 mV to +250 mv with 0.03 mV resolution, referred to the Analog input.
Sampling intervals	Hardware 500 ps, 1 ns or 2 ns real-time sampling with one scan per pound; 250 ps interleaved sampling with two scans per second⁴. Software can display 250 ps interpolated sampling from a spectrum sampled at 500 ps.
Record Size (Hardware)	8 bits per sampled point and up to 1.5 M points per record (at 250, 500, 1000 ir 2000 ps/point. Record length selectabel from a minumum of 10 µs to a maximum of 1.5 M points in steps of 512 points.
Spectrum Size (Hardware)	Identical to Record Size, except 24 bits per sampled point, providing rapid hardware summing of up to 65,535 records ub a spectrum.
