This application note describes an analytical method for determination of carbendazim and 3 other fungicide residues in orange juice with easy sample preparation and LC/MS/MS detection. Developed for the 3 most important systemic fungicides, carbendazim, thiabendazole, and imazalil with its metabolite, this method can be easily expanded to include a broader range of pesticides. A simple and rapid extraction procedure provides clean extracts that without any preconcentration allow for detection of analytes at concentrations below 2 ppb. Quantification was performed using triphenyl phosphate as an internal standard. Excellent accuracy (% recovery) and precision (% CV) data were obtained for three concentration levels: 10, 50, and 250 ppb of each analyte.

This application note describes a rigorous QC column testing approach that employs active tests probes to verify the inertness performance of modern GC capillary columns.

An Agilent 1290 Infinity LC System is optimized for the lowest possible extra-column volume, to ensure minimal band broadening and optimal results from a small dimension, Agilent ZORBAX RRHD Eclipse Plus C18, 2.1 × 50 mm, 1.8 µm column. Improvements to isocratic and gradient analyses are evident, with the early eluting peaks from the isocratic analysis showing the greatest improvement of up to a 58% increase in efficiency (k’ = 1.6). Gradient analyses are improved by 24 to 32% with respect to conditional peak capacity (k’ = 1.3 to 5.3). Additionally, there is no strong correlation between flow rate and the effect of extra-column volume, with respect to column performance for isocratic and gradient analyses.

This application note introduces a method to enable DBS analysis of basic drugs on Agilent Bond Elut Dried Matrix Spotting (DMS) cards, which is achieved by optimizing desorption conditions.

A method has been developed on the Agilent 7000 GC Triple Quadrupole GC/MS/MS system for the analysis of foods for 20 chemicals that may be present in printing inks applied to the external surface of cartonboard packaging material. These substances may diffuse through the cartonboard or set-off onto the food contact surface and then migrate into food. The method described is suitable for the reliable determination of ink substances in packed foods at single-figure parts-per-billion (ppb, µg/kg) levels.

This document describes a multi-residue analysis using an Agilent J&W FactorFour VF-35ms column for PAHs, PCBs, and OCPs. PAHs are compounds with two or more aromatic rings formed during incomplete combustion or pyrolysis of organic matter. OCPs are pesticides containing carbon, hydrogen, and chlorine atoms that break down slowly, persist in the environment, and bioaccumulate in organisms. PCBs are characterized by two phenyl groups with varying numbers of chlorine atoms and are used in various industrial and commercial applications. The method allows for the analysis of 16 EPA PAHs, 17 PCBs (including 6 EU marker PCBs), and 24 common OCPs in a single run at different concentration levels.

This application note provides detailed instructions on how to use the Stratagene Mx3000P QPCR system to detect and quantify various agricultural and economically important fungi.

This Application Note describes the transfer of a United States Pharmacopeia (USP) method for prednisolone from normal phase HPLC to SFC using the Agilent 1260 Infinity Hybrid SFC/UHPLC System. The results show that the SFC method meets the system suitability criteria, is 4x faster, and results in 17x lower solvent expenses. Robustness tests on the SFC method demonstrate excellent robustness for routine analysis.

The LTC ®2435/2435-1 are 2.7V to 5.5V micropower 20-bit differential ∆Σ analog to digital converters with integrated oscillator, 3ppm INL and 0.8ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, the LTC2435 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user defined rejection frequency. The LTC2435-1 can be con- figured for better than 87dB input differential mode rejec- tion over the range of 49Hz to 61.2Hz (50Hz and 60Hz ±2% simultaneously). The internal oscillator requires no external frequency setting components. The converters accept any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The full- scale differential input range is from –0.5VREF to 0VREF.

The LTC1983-3/LTC1983-5 are switching power supplies that can produce negative voltage outputs with a maximum output current of 100mA.
