Abstract Fluorescamine has been shown to be a promising derivatizing reagent for the room temperature phosphorescence analysis of primary amino acids. The fluorescamine concentration used for derivatization in solution was 600 μg/ml and for direct derivatization, 1160 μg/ml. For derivatized primary amino acids the limits of detection were found to be between 0.8 ng and 2.9 ng with linear dynamic ranges between 2 and 3 orders of magnitude. 相似文献

In-phase and quadrature-phase (I/Q) signals often need to be formed in the laser interferometric vibration measurement technique. To avoid the disadvantages of traditional I/Q signals forming methods such as effect of piezoelectric ceramic (PZT) for generating high frequency carrier, or optical configuration with complicated structure, a novel interferometric vibration measurement sensor with quadrature detection is proposed. The sensor utilizes simple optical configuration which contains 1/8 wave plate to generate two I/Q signals, then the signals were processed by arctangent algorithm which is compiled by Labview software through data acquisition card. Theoretical analysis and experimental Lissajous figures synthesis prove the phase orthogonality of the two signals. The experimental results indicate that the system can measure the vibration displacement accurately. 相似文献
