Often, treatment of samples with fluorescence labeling agent reacts with primary and secondary amines to give a fluorescent compound. This is especially important for detecting amino acids in protein hydrolyzates. Fluorescence detectors may also be integrated into a high performance liquid chromatographic (HPLC) system. [Pg.156]

In 1993, the incidence of antimicrobials in car tanker milk and the suitability of different tests for the detection of antimicrobials on the MRL level has been examined in Northern Germany using an integrated detection system (14). This system comprised microbial inhibitor tests for screening, immunochemical tests for preliminary confirmation, and high-performance liquid chromatography (HPLC) for final confirmation either in a parallel or a subsequent fashion in case of positive or questionable screening results. [Pg.465]

The use of high performance liquid chromatography (HPLC) on-line or off-line is an essential feature for peptide mapping to integrate the removal of buffers and salts (purification) and the separation of analytes (preconcentration) with mass spectrometry. With on-line LC/MS approaches, low flow rates (<100pL/min) have been demonstrated to provide maximum sensitivity with ESI techniques for the analysis of proteins. In the work performed by Arnott and... [Pg.73]

The end products of acid and enzymatic hydrolysis of corncob and sugarcane bagasse were analyzed by using a high-performance liquid chromatograph (Waters, Milford, MA) equipped with a Rheodyne automatic injector with a 20- iL injection capacity loop, a Shodex Sugar SC 1011 column, and an integrator model 747 with a model 410 RI detector. The mobile phase was deionized water, and the flow rate was adjusted to 0.8 mL/min. [Pg.1007]

Equipment and expertise. Synthesis requires dedicated laboratory space and equipment. Protein synthesis is best done with the aid of a peptide synthesizer which is capable of optimal step-wise yields. Purification using reverse-phase high-performance liquid chromatography (RP-HPLC) is an integral part of the procedure (16), so at least one preparative and one analytical HPLC systems is needed. Access to electrospray mass spectrometry is essential. [Pg.48]

Based on the quantity of data and the complexity of the process, an enterprise operational informatics system must be robust and scalable. It should also integrate with analytical instrumentation such as high performance liquid chromatography (HPLC) MS to verify compound identity. A recent review of HTS informatics provides a compact overview of the key informatics elements of HTS operations and data handling (Ling, 2008). [Pg.235]
