This Application Note describes the development of conventional HPLC and Rapid Resolution LC (RRLC) methods for the analysis of Buplerui (Chaihu). A comparison of fingerprint chromatograms of different Buplerui samples showed different peak profiles of different TCMs collected from different places. The method for the Agilent 1200 Series Evaporative Light Scattering Detector (ELSD) was optimized to achieve maximum response. A quantitative method was developed to determine the six types of saikosaponins in different TCMs and their preparations.

Agilent's Poroshell 300 reversed-phase HPLC columns offer higher resolution and flow rates for faster and more efficient separation of peptides, proteins, and antibodies.

This Application Note describes a simple, sensitive quantification method for lovastatin in human plasma, based on a liquid chromatography-electrospray ionization-tandem mass spectrometry (LC/ESI/MS/MS) technique. Solid phase extraction was used for the extraction of lovastatin from plasma, and simvastatin was used as the internal standard. For quantification, the triple-quadrupole MS was used in multiple reaction monitoring (MRM) mode. The monitored transitions were m/z 405.4 to 199.2 for lovastatin and m/z 419.1 to 199.2 for simvastatin. A linearity coefficient of R2 > 0.99 was observed over a wide range of 0.1 ppb to 50 ppb of lovastatin in human plasma. Several methods are currently available for the quantification of this statin, but sensitivity and shorter runtime were the major challenges in those methods. The advantages of the method described here are simplicity, short runtime (1.2 minutes) and better sensitivity through MRM.

This paper describes the use of gas chromatography coupled with triple quadrupole mass spectrometry (GC/MS/MS) to screen pesticides in Traditional Chinese Medicine (TCM) at levels as low as 1 ppb. The Triple Quadrupole mass spec- trometer, when used in Multiple Reaction Monitoring (MRM) mode, can dramatical- ly remove matrix interferences and significantly increase the effective signal-to- noise ratio (S/N).

This article introduces the characterization of lavender oil using Agilent J&W DB-1ms Ultra Inert capillary GC columns. Gas phase analytical techniques including GC/MS, GC x GC, and GC/TOF were used to analyze the main components in lavender oil samples from several suppliers. The well-resolved components were then identified using a single quad GC/MS versus NIST Library 5.01, and the identified peaks served as the fingerprint for analysis. The same separation using GC-FID could be used to evaluate subsequent samples quickly and cost effectively. The well-resolved, sharp peaks observed on the Agilent J&W DB-1ms Ultra Inert column made this approach possible.

SN54173, SN54LS173A, SN74173, SN74LS173A 4-bit D-type registers with 3-state outputs. 3-state outputs can directly interface with the system bus. Gated output control lines can be used to enable or disable the outputs. The completely independent clock virtually eliminates the restrictions for operating in one of two modes: parallel load or do nothing (hold). For application as bus buffer registers. Plastic small-outline (D) packages, ceramic flat (W) packages, ceramic chip carriers (FK) and standard plastic (N) and ceramic (J) DIPs are packaging options.
