A new method was developed for determination of methomyl in water samples by combining a dispersive liquid-liquid microextraction (DLLME) technique with HPLC-variable wavelength detection (VWD). In this extraction method, 0.50 mL methanol (as solvent) containing 20.0 microL tetrachloroethane rapidly injected syringe into 5.00-mL sample the analyte, thereby forming cloudy solution. After phase separation centrifugation 2 min at 4000 rpm, enriched analyte settled (8 +/- 0.2 microL) bottom...
Abstract Buried pipelines are an essential component of the urban infrastructure modern cities. Traditional buried pipes mainly made metal materials. With development material science and technology in recent years, non-metallic pipes, such as plastic ceramic concrete increasingly taking place from various pipeline networks water supply, drainage, heat, industry, oil, gas. The location technologies for have become mature, but detection still developing. In this paper, current trends future...
A new method for the determination of four aromatic amines in water samples was developed by using dispersive liquid-liquid microextraction (DLLME) technique combined with HPLC-variable wavelength detection (HPLC-VWD). In this extraction method, 0.50 mL methanol (as solvent) containing 25.0 microL tetrachloroethane rapidly injected a syringe into 5.00 sample. Accordingly, cloudy solution formed. After centrifugation 2 min at 4000 rpm, fine droplets analytes were sedimented bottom conical...

The prevailing advanced method for early overflow monitoring involves the comparison of surface mud pump injection flow rate with downhole annular return rate. Despite its widespread use, this indirect leaves room enhancement, particularly in performance. Real-time bidirectional information near drill bit presents a more direct and precise approach to detection. This article introduces novel electromagnetic measurement system (BEMFS). Initially, an in-depth exploration is conducted into...
