The detectormakes 100 absorbance readings per second. The time constant allows you to producea rolling average of readings to make a more manageable number of points to plotor export to workstation. It allows you to specify a number of seconds,and averages the readings within that time.Thedefault setting is 1s。 This meansthat 100 readings are averaged to give one date point that is plotted or exportedto a device connected to the signal out port. You can smooth noisy date by raisingthe value,or make the detector more sensitive(for example,if you are acquiring narrow peaks)by lowering the value.
该检测器每秒钟提供100个吸光度的数据。时间常数就是设定一个数字,使得这写数据里给出一个更有意义的平均值,发送给积分仪或者工作站。它让操作人员指定一个数据,andaverages the readings within that time.通常默认值是1s,意思是1s的一百个采集数据将给出一个点给工作站。增加时间常数可以降低噪音,减少时间常数可以增加灵敏度。 通常是以最窄峰的信息来确定时间常数的。不过,国内的用户一般很少设置该数值,都是以默认值1s或2s来进行数据处理的;
