This short review provides the recent progresses on continuous monitoring of atmospheric ozone. The analytical performance is defined in US-EPA 40 CFR Part 53, and Federal Equivalent Method for ozone adopts an ultraviolet photometry to meet the definition. Chemical monitoring systems including spectrophotometry with dye bleaching, chemiluminescence, and bioluminescence have been developed to satisfy the analytical performance. Changes in the electric resistance of semiconductors are also utilized for the measurements. Some of the proposed instruments have been applied to the monitoring of ozone in the ambient air, and reliable results are demonstrated.

This work proposes a Flow Injection Analysis (FIA) system to determine neomycin in pharmaceutical formulation, utilizing ninhydrin as chromogenic reagent, with absorbance signal measured at 570 nm. To check the significant flow parameters, a screening with 2 4 full factorial designs was optimized, and a Doehlert matrix used to obtain the optimum variable values. The method presents two linear responses ranging from 29.8 up to 300 mg L -1 (r 2 =0.9933) and 800.0 up to 2500 mg L -1 (r 2 =0.9926). The Limits of Detection and Quantifications were 8.94 mg L -1 and 29.8 mg L -1 , respectively. The readings frequency was of 33 reading h -1 . The method accuracy was checked through comparison with HPLC method and the results found were similar (t-test, 95% confidence level). The method was applied in pharmaceutical samples with very good performance and the precision (RSD) was always below 8.0%. The reagent and sample consumption was very low, what is in agreement with the green chemistry concept
本文提出了一种以茚三酮为显色剂，在570 nm处测量吸光度信号的流动注射分析(FIA)系统。为了检查显著的流量参数，优化了24个全因子设计的筛选，并使用Doehlert矩阵获得最佳变量值。该方法在29.8 ~ 300 mg L -1 (r2 =0.9933)和800.0 ~ 2500 mg L -1 (r2 =0.9926)范围内呈线性响应。检出限为8.94 mg L -1，定量限为29.8 mg L -1。读数频率为33次，读数h -1。与高效液相色谱法比较，结果相似(t检验，95%置信水平)。该方法适用于药品样品，精密度(RSD)均在8.0%以下，性能良好。试剂和样品消耗非常低，符合绿色化学的理念

The development and application of a new simultaneous injection- effective mixing flow analysis (SIEMA) is described. The manifold is based on one syringe pump with a two-way solenoid valve, a set of holding coils and three-way solenoid valves, two multiport connectors, a mixing coil and a detector. The system is compact and is controlled by a laptop computer. Some analytical features of SIEMA are compared with other flow-based systems in terms of mixing efficiency, reagent consumption and sample throughput. Applications of the SIEMA system are demonstrated for environmental and clinical analysis.
