This document describes an effective, sensitive triple quadrupole LC/MS method with a simple, fast and economic sample preparation technique for the quantitation of 12 multi-plant growth regulators (PGR) in grape samples. Plant hormones or phytohormones are chemicals that regulate plant growth. Manmade compounds, or PGRs are used to regulate the growth of cultivated plants, weeds, and in vitro growth plants and plant cells. Synthetic PGRs are also used in various techniques such as cutting, grafting, and micropropogation. PGRs activate cellular responses such as cell death. Some have the ability to adversely affect human cancer cells. Because the European Union has listed these compounds, they are required to be measured.

Agilent Bond Elut Plexa polymeric SPE reduces ion suppression for better sensitivity and low LOD and LOQ. Beta blockers are extracted with excellent correlation coefficients, recoveries, and % RSD.

Agilent Bond Elut Plexa PCX is a cation exchange solid phase extraction product with hydroxylated surface, which can reduce the interaction between endogenous material in biological samples and the solid phase extraction sorbent, thereby reducing ion suppression and improving sensitivity.

This Application Note describes the analysis of milk by on-chip electrophoresis with the Agilent Protein 80 kit and the Agilent 2100 Bioanalyzer. Advantages of this method for milk protein analysis in comparison to conventional SDS-PAGE include: • Fast, reproducible and robust all in one method, replacing gel electrophoresis, staining and densitometric analysis • Easy sample comparison by electropherogram overlay for protein assignment within a chip or in between chips • Automated quantitative analysis for individual protein components

This document describes the fine tuning features of products such as CLP-220, N-100, P-65, P-70, YDP-131/151/213/323/S30, including pitch adjustment and default setting range.

This article describes the method and conditions for pesticide analysis by GC/ECD using Agilent J&W FactorFour VF-5 Pesticides and VF-1701 Pesticides columns. The method effectively separates EPA 8081 pesticides and provides peak identification data for VF-1701 Pesticides and VF-5 Pesticides columns.

This application note describes a GC/MS method that resolves all EU and EPA PAHs, and their known interferences, with the Select PAH column in a single run. The method uses enhanced column selectivity and an optimized oven program to resolve all PAHs, including those that co-elute with other PAHs.

This document describes the error information of CLP-220, N-100, P-65, P-70, YDP-131/151/213/323/S30, including the accuracy of fine tuning the pitch, the step of fine tuning the pitch and the range of fine tuning the pitch.

This document provides errata for the Fine tuning of the Pitch feature of CLP-220, N-100, P-65, P-70, YDP-131/151/213/323/S30 keyboards. It corrects the incorrect information regarding the pitch adjustment steps and range. The document provides the correct steps and range, along with the explanation of the default setting and adjustment units. It also explains the frequency adjustment in the 440Hz region and provides an example operation.

The AT1396A/B/C/D is a 6-channel DC-DC converter from Aimtron. It can be used for CCD bias, LED driver, etc.

This article describes the method of detergent removal using Agilent Bond Elut OMIX SCX pipette tips. The Bond Elut OMIX SCX pipette tips have good adsorption capacity and flow characteristics, which can quickly and effectively remove detergents.

EMF6 is a dual transistor package used for power management circuits. It features a power switching circuit and reduced mounting cost and area.

This application note describes a method for identifying oxidation sites on a monoclonal antibody (mAb) using an Agilent 1260 Infinity HPLC-Chip/MS system coupled to an Agilent Accurate-Mass 6520 Quadrupole Time-of-Flight (Q-TOF) LC/MS. A monoclonal antibody was oxidized by treatment with hydrogen peroxide to stimulate potential oxidative modifications that may occur during the manufacturing process. The accurate mass measurement of the 6520 Q-TOF LC/MS combined with Agilent MassHunter BioConfirm software facilitated easy identification of the oxidation sites. Peptides containing amino acid residues such as methionine and tryptophan, which are sensitive to oxidation, were easily identified using this approach.
