Enhancement of Linearity and Response in Charged Aerosol Detection
نویسندگان
چکیده
Raw data collected by analytical detectors rarely correlates directly to the data points that are analyzed by the chromatographic software. Rather the data has already been manipulated in some way within the detector, typically post data collection. The most common examples are filtering and smoothing algorithms. The power transformation is simply another internal data manipulation aimed at improving the outputted data quality without changing the true separation. The use of power transformation can often improve the appearance of non-linear detectors. While these settings are typically not fully disclosed or described to the end user, they may be implemented to improve the appearance or linearity of the results.

Effects of densities of brominated flame retardants on the detection response for HPLC analysis with a corona-charged aerosol detector.
Dependence of the response of a corona-charged aerosol detector (corona CAD) on the concentration and densities of brominated flame retardants and some related substrates was studied. The calibration curves of the substrates did not show linearity and the substrate with a lower density exhibited the stronger response. Regardless of the solvents (chloroform or toluene), and the injected volume o...
متن کاملTapered Optical Fiber Coated with ZnO Nanorods for Detection of Ethanol Concentration in Water
This work presents ZnO nanorods coated multimode optical fiber sensing behavior in response to ethanol solution. The sensor operates based on modulation of light intensity which arises from manipulation of light interaction with the ambient environment in sensing region. For this purpose, two steps are experimentally applied here; etching and then coating fiber with ZnO nanorods to provide stro...
متن کاملبهینهسازی پاسخ دزیمتری نوترون در بازه انرژی حرارتی و سریع برای آشکارساز دیودی
During the last few years, real time gamma and neutron dosimeters have been developed and semiconductor diodes are frequently used in these dosimeters. Semiconductor diodes are used to charged particle detection. For sensitizing the detector to neutrons, a converter layer is contacted on the front surfaces of them. Incident neutrons interact with the converter and produce charged particles that...
