37. The integration factor controls the bandwidth of the chromatograph signal It is necessary to match the bandwidth of the input signal to that of the analysis algorithms in the Controller Assembly This prevents small short duration perturbations from being recognized as true peaks by the program It is therefore important to choose a Peak Width that corresponds to the narrowest peak in the group under consideration Peak Detection For normal area or peak height concentration evaluation the determination of a peak s start point and end point is automatic The manual determination of start and end points is used only for area calculations in the Forced Integration mode Automatic determination of peak onset or start is initiated whenever Integrate Inhibit is turned off Analysis is started in a region of signal quiescence and stability such that the signal level and activity can be considered as baseline values Peak Detection 1 24 INTRODUCTION Peak Detection Model 700 Having initiated a peak search by turning Integrate Inhibit off the Controller Assembly performs a point by point examination of the signal slope This is achieved by using a digital slope detection filter a combination low pass filter and differentiator The output is continually compared to a user defined system constant called Slope Sensitivity A default value of 8 is assumed if no entry is made Lower values make peak onset detection more sensitive
38. and higher values make detection less sensitive Higher values 20 to 100 would be appropriate for noisy signals e g high amplifier gain Onset is defined where the detector output exceeds the baseline constant but peak termination is defined where the detector output is less than the same constant Sequences of fused peaks are also automatically handled This is done by testing each termination point to see if the region immediately following it satisfies the criteria of a baseline A baseline region must have a slope detector value less than the magnitude of the baseline constant for a number of sequential points When a baseline region is found this terminates a sequence of peaks A zero reference line for peak height and area determination is established by extending a line from the point of the onset of the peak sequence to the point of the termination The values of these two points are found by averaging the four integrated points just prior to the onset point and just after the termination points respectively JULY 2007 INTRODUCTION 1 25 Model 700 The zero reference line will in general be non horizontal and thus compensates for any linear drift in the system from the time the peak sequence starts until it ends In a single peak situation peak area is the area of the component peak between the curve and the zero reference line The peak height is the distance from the zero reference line to the maximum poi
