This document presents an example of permanent gas analysis using the Agilent 490 Micro GC, including the separation of helium, neon, and hydrogen. The product offers the advantages of ease of use and fast analysis, with a total analysis time of less than 40 seconds.

This file describes the chiral separation and enantiomeric excess (EE) determination of three model chiral compounds using Supercritical Fluid Chromatography using the Agilent 1260 Infinity Analytical SFC system. The low detector noise of the system due to the SFC pump technology resulted in excellent sensitivity for trace analyte detec- tion of chiral impurities. When applying method optimization sufficient resolution was achieved for all compounds even under mass overload conditions. This allowed for the quantitation of impurities at 0.05 to 0.1% levels.

This document describes the method of using the Agilent 1260 Infinity Analytical SFC system for fast and ultra-fast SFC analysis.

This method can increase sample throughput and reduce cost of ownership.

This article describes the use of Agilent PLgel columns and gel permeation chromatography (GPC) for polymerization studies. GPC separates molecules in solution based on their size, making it ideal for monitoring the effect of process variables on polymer synthesis. The study focuses on the polymerization of soya oil, and GPC analysis is used to observe the progress of the reaction and the formation of high molecular weight species.

This application note describes the use of Agilent PLgel columns and gel permeation chromatography to analyze petroleum. Petroleum analysis is a major source of organic chemicals for the petrochemical industry.

The MAX349/MAX350 are 8-channel and dual 4-channel serially controlled multiplexers (muxes). These muxes conduct equally well in either direction. On-resistance (100Ω max) is matched between switches to 16Ω max and is flat (10Ω max) over the specified signal range. These CMOS devices can operate continuously with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. Each mux can handle rail-to-rail analog signals. The off-leakage current is only 0.1nA at +25°C or 5nA at +85°C. Upon power-up, all switches are off and the internal shift registers are reset to zero. The serial interface is compatible with SPI™/QSPI™ and MICROWIRE™. Functioning as a shift register, it allows data (at DIN) to be clocked in synchronously with the rising edge of clock (SCLK). The shift register’s output (DOUT) enables several MAX349s or MAX350s to be daisy chained. All digital inputs have 0.8V or 2.4V logic thresholds, ensuring both TTL and CMOS-logic compatibility when using ±5V supplies or a single +5V supply.

This application note describes a method for accelerating the analysis of Group 4 pharmaceuticals in EPA-1694 using an Agilent 1290 Infinity UHPLC and an Agilent ZORBAX RRHD HILIC Plus column. All compounds provide excellent peak shapes, while the flow rate and sample throughput are increased by four times the original rate.

This application note describes a non-targeted metabolomic analysis approach to the classification of wine varieties, employing LC/QTOF MS and MassHunter Workstation software. Molecular feature extraction, data filtering, and statistical analysis utilizing ANOVA and PCA identified 26 marker compounds that were then used to build a PLSDA prediction model. An overall accuracy of 95.6% in discriminating between Cabernet Sauvignon, Merlot and Pinot Noir red wine varieties was obtained using the model. This approach may be widely applicable to the analysis and characterization of foods.

The MAX2264/MAX2265/MAX2266 evaluation kits (EV kits) simplify evaluation of the MAX2264/MAX2265/ MAX2266 power amplifiers (PAs), which are designed for operation in IS-98-based CDMA, IS-136-based TDMA, and PDC cellular phones operating in the 900MHz range. The kits enable testing of the devices’ RF performance and require no additional support circuitry. The EV kits’ signal inputs and outputs use SMA connectors to facilitate the connection of RF test equipment. Each kit is assembled with either the MAX2264, MAX2265 or MAX2266 and incorporates input and output matching components optimized for the 824MHz to 849MHz RF frequency band. These EV kits are capable of operating at RF frequencies from 750MHz to 1000MHz with the appropriate matching components.
