A simple, cost-effective analysis combining solventless extraction, thermal desorption, and determination of volatile organic compounds (VOCs) was developed and validated. A needle trap device (NTD)… Expand
Bioanalytical Application of SERS Immunoassay for Detection of Prostate-Specific Antigen
We demonstrate the possible application of the sandwich type surface-enhanced Raman scattering (SERS) immuno-assay using antigen-antibody binding for detection of prostate-specific antigen (PSA) in… Expand
Development and application of needle trap devices.
Needle trap devices (NTDs), like solid-phase microextraction (SPME) fibers, represent a new approach to one-step, solvent-free sample preparation and injection. New NTDs, packed with divinylbenzene… Expand
Development of a syringe pump assisted dynamic headspace sampling technique for needle trap device.
This paper describes a new approach that combines needle trap devices (NTDs) with a dynamic headspace sampling technique (purge and trap) using a bidirectional syringe pump. The needle trap device is… Expand

The possibility of sampling the free and particle-bound concentrations of organic compounds was studied using two different sampling techniques at the same time: needle trap device (NTD) and… Expand
Simple sample transfer technique by internally expanded desorptive flow for needle trap devices.
Needle trap devices (NTDs) are improving in simplicity and usefulness for sampling volatile organic compounds (VOCs) since their first introduction in early 2000s. Three different sample transfer… Expand
Simultaneous sampling and analysis of indoor air infested with Cimex lectularius L. (Hemiptera: Cimicidae) by solid phase microextraction, thin film microextraction and needle trap device.
Air in a room infested by Cimex lectularius L. (Hemiptera: Cimicidae) was sampled simultaneously by three different sampling devices including solid phase microextraction (SPME) fiber coatings, thin… Expand

Spectral Responses of Light‐Emitting Diodes as a Photodiode and Their Applications in Optical Measurements
Spectral responses of four light-emitting diodes (LEDs) were investigated because their uses as a photodiode are growing these days. An LED showed reasonable sensitivity to shorter wavelengths which… Expand
Surface characterization of the high voltage LiCoO2/Li cell by X-ray photoelectron spectroscopy and 2D correlation analysis
Abstract In this study, we demonstrated the surface reaction in a LiCoO2/Li cell under high voltage condition and characterization of the composition and properties of electrode–electrolyte interface… Expand
