The PD16855A/B/C/D is a dual high-side switch from NEC for use on the power supply bus of the Universal-Serial-Bus (USB). It features two Pch power MOSFETs in the switch part, each with low on resistance (100 mΩ TYP.), as well as over current detection, thermal shutdown and under voltage lockout circuits. The over-current-detect result can be reported to the controller by flag-pin.

PIC12C508 and PIC12C509 are 8-bit microcontrollers packaged in 8-lead packages. They are based on the Enhanced PIC16C5X family.

This Application Note demonstrates that the combination of HPLC with the Agilent 385-ELSD Evaporative Light Scattering Detector provides a better alternative for the sensitive analysis of polar lipids. Evaporative light scattering detection is universal and not dependent on the optical properties of the compound, making it ideal for analysis of lipids such as cholesterol and phosphatidylcholine that have very poor UV chromophores. ELS detection recognizes any compound that is less volatile than the mobile phase. This makes ELS detection fully compatible with HPLC elution gradients. ELS detection also eliminates the need for pre-analysis derivatization to enhance UV absorbance, facilitating rapid determination of lipids in complex matrices.

This Application Note describes how the Agilent 380-ELSD Evaporative Light Scattering Detector was used to analyze herbicides at low temperature. The detector is designed to evaporate highly aqueous mobile phases at ambient temperature, providing a solution for detecting thermally sensitive compounds.

This is a PDF document about Hall-effect latches, which mainly introduces its features and characteristics, including symmetrical response, 4.5V to 18V operating range, open-collector output, reverse battery protection, activation with small, commercially available permanent magnets, solid-state reliability, small size, superior temperature stability and resistance to physical stress.

This application note describes the combination of mass spectrometry and evaporative light scattering detection as a powerful tool for the analysis of pharmaceuticals. An Agilent 500 Ion Trap MS was coupled to an Agilent 385-ELSD Evaporative Light Scattering Detector for quantification of Haloperidol and its metabolites, Diazepam and Verapamil, and Ibuprofen and ß-cyclodextrin. Mass spectrometry is highly sensitive and widely used as an information rich detector, but it is not universal and some analytes do not ionize well using standard ion sources. This problem can be overcome by coupling to another kind of detector such as an evaporative light scattering detector, which has many advantages over refractive index and ultraviolet detectors.

This application note describes the use of a quick, easy, cheap, effective, rugged, and safe (QuEChERS) AOAC sample preparation approach for the extraction and cleanup of 13 pesticide residues representing various pesticide classes in spinach. The method involves initial extraction in a buffered aqueous/acetonitrile system, an extraction/partitioning step after the addition of salt, and a cleanup step using dispersive solid-phase extraction (dispersive SPE). A modified method with the addition of toluene was employed to address the significant loss of planar pesticides caused by graphitized carbon black (GCB) in dispersive SPE. The presence of the target pesticides in the spinach extracts were then determined by liquid chromatography coupled to an electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) operating in positive ion multiple reaction monitoring (MRM) mode. The method was validated in terms of recovery and reproducibility for all of the analytes of interest, with a 5 ng/g limit of quantitation (LOQ) for pesticides in spinach. The mean recoveries ranged between 64% and 108% (average of 91.9%), with RSD.

the uc37131/2/3 is a family of smart power switches that can drive resistive or inductive loads from the high side or low side. uc37132 offers 14-pin (dip), 16-pin (soic), or 20-pin (clcc) packages and can accommodate both low side (load to vcc) or high side (load to gnd) configurations. uc37131 and uc37133 are exclusively for a low side or a high side configuration respectively and both are available in an 8-pin package. both high side and low side configurations provide high current switching with low saturation voltages that can drive resistive or inductive loads. the input to the switch is driven by a low voltage signal, typically 5v. in addition, uc37132 features adjustable hysteresis. the output of the device can switch to high voltage (72v) or low voltage (6v).

The qualitative and quantitative analysis of pesticides at trace levels in baby food matrices using UHPLC and triple quadrupole MS is demonstrated. Sample preparation is performed using an Agilent Bond Elut QuEChERS kit for extraction and dispersive SPE. The extracts are analyzed by LC/MS/MS on an Agilent 1290 Infinity LC system coupled to an Agilent 6460 triple quadrupole LC/MS using Dynamic MRM. The method and extraction performance were evaluated in terms of repeatability, linearity and sensitivity. Moreover the influence of the additional dispersive SPE cleanup was investigated. Detection limits were between 500 ng/kg and 10 ng/kg (ppt), which is much lower than the maximum residue level (MRL) of 10 µg/kg (ppb) imposed by the European Union.

An HPLC-Florescence Detection (FLD) method was developed and validated for the determination of sixteen polycyclic aromatic hydrocarbons (PAHs) in fish fillets. The method employs a quick, easy, cheap, effective, rugged and safe (QuEChERS) multiresidue sample preparation procedure adopted from the Association of Analytical Communities (AOAC) Official method 2007.01 for extraction and cleanup. The analytes were separated on an Agilent ZORBAX Eclipse PAH HPLC column (4.6 mm × 50 mm, 1.8 µm) by gradient elution with a binary system of acetonitrile - water and subse- quent fluorescence detection set at appropriate excitation and emission wavelengths. The analyte recoveries ranged from 83.4% to 101% with relative standard deviations ranging from 0.6 to 1.9% at three different fortification levels. The limits of detection and quantification ranged from 0.04 to 0.84 and 0.1 to 2.80 ng/g, respectively.
