This document introduces a feasibility study of a capillary electrophoresis-mass spectrometry (CE-MS) technique for toxicological drug screening in blood samples. The study shows that the Agilent LC/MSD Trap system can detect drugs at levels as low as 20 ng/mL in whole blood, suggesting that it may be a suitable tool for screening whole blood samples for drugs. Additionally, the system's capability of generating MSn data allows reliable identification of detected drugs, suggesting that both screening and identification of drugs can be accomplished in one or two injections using the same instrument system.

This Application Note describes methods of using the Agilent Capillary Electrophoresis (CE) system to separate single- and double-stranded DNA, single-stranded RNA and antisense oligonucleotides. Oligonucleotides with a chain length of 5 to 80 nucleotides are separated using polymer solution A and polymer solution B. The application note describes how to achieve high reproducibility in separations of oligonucleotides.

This application note describes a method for the analysis of aromatic amines in leather extracts using CE-MS. This method provides specific identification of analytes in complex matrices that would present difficulties for HPLC. Organic extracts of leather fit this description exactly, therefore CE-MS is the method of choice.

This document describes the use of capillary electrophoresis coupled with electrospray ionization mass spectrometry (CE-ESI-MS) to analyze hallucinogenic mushroom extracts. The data presented here demonstrate feasibility. Additional method development and/or validation may be required for routine use.

This paper describes the analysis of drugs of abuse using capillary electrophoresis coupled with electrospray ionization mass spectrometry (CE-ESI-MS). The unique identification of drugs was achieved by observing protonated molecular ions and characteristic fragment ions. The experimental results demonstrate the feasibility of the method, but additional method development and/or validation may be required for routine use.

The study proposes an optimized method for the analysis of tropane alkaloids by CE-ESI-MS. The results show that the method has high selectivity and sensitivity and is suitable for the quantitative analysis of tropane alkaloids in biological samples.

This application note describes a method for quantifying three alkaloids in the stem of various mahonia species: berberine, palmatine, and jatrorrhizine. The method uses capillary electrophoresis (CE), which is particularly suited to the analysis of plant extracts because of its ability to deal with complex or “dirty” sample matrices.

This document is about DAC1020 and DAC1220, which are respectively 10- and 12-bit binary multiplying digital-to-analog converters with excellent temperature tracking characteristics. They use CMOS current switches and drive circuitry to achieve low power consumption and low output leakage.

The DAC101S101 is a full-featured, general purpose 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes just 175 µA of current at 3.6 Volts.

The DAC1006, DAC1007, and DAC1008 are advanced CMOS-Si-Cr 10-, 9-, and 8-bit accurate multiplying DACs designed to interface directly with the 8080, 8048, 8085, Z-80, and other popular microprocessors. These DACs appear as a memory location or an I/O port to the microprocessor, and no interfacing logic is needed. When combined with an external amplifier and voltage reference, these devices can be used as standard D-A converters and are particularly attractive for multiplying applications (such as digitally controlled gain blocks) because their linearity error is essentially independent of the voltage reference. They are also attractive in audio signal processing equipment as audio gain controls or programmable attenuators, combining high-quality audio signal processing with digitally based systems under microprocessor control. All of these DACs are double-buffered and can load all 10 bits or two 8-bit bytes, with the data format being left justified. The analog section of these DACs is essentially the same as that of the DAC1020. The DAC1006 series are the 10-bit members of a family of microprocessor-compatible DACs (MICRO-DACs). For applications requiring other resolutions, the DAC0830 series (8 bits) and the DAC1208 and DAC1230 (12 bits) are available alternatives.

This document is the product manual for the DAC10 series of 10-bit monolithic multiplying digital-to-analog converters. It introduces the features and usage methods of the product.
