厂商名称:Signal Recovery
商品名称:数字信号平均器
商品型号:FASTFLIGHT-2
简单信息:在飞行时间质谱领域,从MALDI-TOF、QqTOF到LC/TOF-MS以及GC/TOF-MS,Signal Recovery能提供高质量的数据采集产品。

凭借其采集速率达100平均谱图/秒的能力,FASTFLIGHT-2成为LC/TOF-MS/和GC/TOF-MS应用中优异的数据采集解决方案。色谱技术正在向更短的保留时间发展,使得飞行时间质谱(TOF-MS)获取平均谱图的速度越来越快。对比第一代的数字信号平均器,FASTFLIGHT-2 将TOF谱图处理速度提高了10倍,因而有能力适应更快的色谱仪。

由于使用了采样ADC以及硬件数字信号平均器,FASTFLIGHT-2能处理LC/TOF-MS, GC/TOF-MS, Ion-Trap/TOF-MS 和 MALDI I TOF-MS中碰到的高速离子而不用像在时间数字转换器(TDC)中遭受死区时间的困扰。对比瞬时数字转换器以及数字采样示波器,他们都面临缓慢的软件平均速度,FASTFLIGHT-2传递平均谱图的速度比它们快了好多个数量级。

其创新的,自动关联噪声消减特性意味着FASTFLIGHT-2在QqTOF-MS低速离子应用中也是有效的解决方案,这一领域以前一直被认为都是TDC和时间转换器所独有。

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 averaged3. 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.
