6.8.6 Data output 6.8.7 Specifications Figure 6-88 Analog monitor channel properties A Moments object is required to access the Analog monitor data. To access the data, a List, a graph or an Export object can be added. The analog data can be further processed and displayed the same way as the other data from the Moments object. Input impedance: 10 kΩ Resolution: 12 bit, 2.5mV Range, unipolar: 0V to 10.24V Full scale accuracy: ±1% Linearity: ±0.05% Maximum safe input voltage: ±20V Sampling frequency: 8 Hz Inputs are not low-pass filtered, so high-frequency noise at the inputs can affect accuracy. Many “slow” tranducers will have an upper frequency limit of less than 4 Hz, in which case the Nyquist sampling theorem is satisfied. If the signal may contain frequencies higher than 4 Hz, it should be passed through an anti-aliasing filter (low-pass filter) with a cut-off frequency of 4 Hz, to avoid errors due to under-sampling. 6.9 LIF and Parametric Analysis Add-on This add-on is designed to do calibration for concentration or temperature LIF measurements. It can also be used to do parametric analysis study like the influence of injection pressure on the particles velocity. Installing the “LIF and parametric analysis add-on” adds • a 4 th column in the measurement position table for the input parameters • a curve fitting in the Profile plot object 6-96 BSA Flow Software: Options and Add-ons
6.9.1 Required hardware 6.9.2 Calibration procedure The Analog/Digital input Option is required for concentration or temperature LIF calibration. This chapter describes how to do a Concentration-LIF calibration. This procedure is the similar for other calibration like Temperature-LIF or for other instruments connected to the Analog/Digital Input board requiring a calibration. The purpose of the calibration is to calculate the relation between the LIF signal and a known concentration of dye. This relation will be used afterward as transfer function in the Analog/Digital input properties to calculate the dye concentration corresponding to the measured LIF signal. In the following example, the SignalLIF output is connected to the Analog/Digital Input 4 (AD4) • Step 1: by adding step by step a known quantity of dye, the concentration calibration curve, SignalLIF=f (Dye concentration), is plotted. A Profile Plot is created as a child of the Moments object. Figure 6-89 Example of Concentration-LIF calibration curve • Step 2: Transpose the curve to get the following relation Concentration=f -1 (SignalLIF) BSA Flow Software:Options and Add-ons 6-97
