Analog Image Sensor for Highly-sensitive Spectroscopic Imaging
ABSTRACT In this paper, we propose a highly sensitive laser spectroscopic imaging method without scanning process. We have investigated analog signal processing circuits, which are supposed to be installed to each pixel of a CMOS image sensor. In the imaging method, modulated signal is extracted from background before signal digitization. It gives wider dynamic range compared to conventional im...
متن کاملA Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples
In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...
متن کاملApplication of Thionine Dye for Highly Sensitive and Selective Catalytic kinetic Determination of Osmium
Anew, highly sensitive and selective catalytic kinetic method (CKM) for determination of osmium (VIII) has been established based on its catalytic effect on the oxidation of thionine dye by hydrogen peroxide in alkaline medium. The reaction has been followed spectrophotometrically by measuring the decrease in the absorbance band of thionine at 600 nm. Under the optimum conditions, the proposed ...
متن کاملHighly Sensitive Capacitive Gas Sensing at Ionic Liquid-Electrode Interfaces.
We have developed an ultrasensitive gas-detection method based on the measurement of a differential capacitance of electrified ionic liquid (IL) electrode interfaces in the presence and absence of adsorbed gas molecules. The observed change of differential capacitance has a local maximum at a certain potential that is unique for each type of gas, and its amplitude is related to the concentratio...
متن کاملHighly selective and sensitive fluorescent sensing of oxalate in water.
Effective fluorescent sensing of oxalate in water is significant but still remains a challenge. By using indicator-displacement assays, a readily available macrocyclic copper(II) complex was found to show a sensitive off-on fluorescent sensing for oxalate with high selectivity and high binding affinity (>10(7) M(-1)) in water at neutral pH.
