A direct, sensitive, simple and practical method for the determination of amino acids and glucose in amino acid injection by anion exchange chromatography with integrated pulsed amperometric detection was developed. There is no need for sample pretreatment. The retention behavior of amino acids and glucose on the anion exchange column was investigated using sodium hydroxide and sodium acetate as eluent. When the concentration of sodium hydroxide was changed, the change in the retention times was generally greater for amino acids than for glucose. The difference can be used to improve the separation between amino acids and glucose. When the concentration of sodium acetate was changed, the change in the retention times was generally greater for amino acids containing two carboxyl groups than for amino acids containing only one carboxyl group. The difference can be used to improve the separation between di carboxylic amino acids and mono carboxylic amino acids. In order to separate amino acids and glucose, a ternary gradient elution method with water, sodium hydroxide and sodium acetate as mobile phases was employed. The optimized gradient elution condition for the analysis of 17 amino acids and glucose in amino acid injection was obtained. The time of the gradient elution program was 74 min. Under the optimized conditions and the column temperature of 30 ℃, the detection limits for 17 amino acids and glucose were 0 3 pmol-10 3 pmol. The calibration graphs of peak area for all the analytes were linear in the ranges about two orders of magnitude. The relative standard deviations (RSDs) ( n =5) were 0 7%-3 8%. The recoveries of added standard were 88 3%-104 6%.

A new chemically modified electrode (CME) based on the immobilization of submi-crometer - size Pt particles is fabricated. It is found that the CME exhibits efficiently electro-catalytic oxidation for L - cysteine (L-Cys), glutathione (GSH) and penicillamine (PEN) with relatively high sensitivity. Coupled with HPLC, the CME is utilized for pulsed amperometric detection of these thiols. The results indicate that utilization of pulsed amperometric detection can effectively improve the responses of these thiols because of alternated anodic and cathodic polarizations to clean and reactivate the CME surface. It shows that the peak currents of L - Cys, GSH and PEN are linear to their concentrations with the calculated detection limit of 1. 1 × 10 -7, 1. 8× 10 -1 and 3. 8 × 10 -7 mol/L, respectively. The method has been successfully applied to assess the contents of L - Cys and GSH in rat striatal microdialysates.

该文研究了亚微米铂粒子修饰电极的制备方法。并将该修饰电极与高效液相色谱脉冲安培检测法(HPIC-PAD)联用,分别检测了半胱氨酸(L-Cys)、谷胱甘肽(GSH)和青霉胺(PEN)三种巯基化合物。结果表明该修饰电极对这三种巯基化合物有良好的催化氧化作用;由于PAD的周期性的阳极高电位和阴极低电位能很好地清洗和再活化电极表面,应用PAD方法能有效提高巯基化合物的电流响应。此外,结果还表明,L-Cys、GSH和PEN的电流响应与其浓度呈现良好的线性关系,其检出限分别为1.1×10~(-7)mol/L、1.8×10~(-7)mol/L和3.8×10~(-7)mol/L(S/N=3)。与微渗析技术联用,该方法成功地用于大鼠脑中L-Cys和GSH的测定。这为电分析化学在临床医学、生理学等生命科学中的应用提供了新的手段。
