A novel UPLC-UV method was developed for analysis of timolol in human plasma using a simple, fast, and cost effective ion-exchange SPE procedure, followed by separation on a C 18 UPLC column with a mobile phase consisting of acetonitrile, phosphate b

Aerosol-based detection methods for HPLC in which HPLC effluent is converted to an aerosol and detected optically have been employed in the past. This paper describes a new aerosol-based detection method for HPLC, which we name aerosol charge detecti

Hydroxymethanesulfonate (HMS), a product of the heterogeneous reaction between S(IV) and HCHO, was measured in atmospheric aerosol samples collected at two locations indicating it can exist outside of clouds. Sampling was performed through collection

The use of alternate fuels has been proposed as a method of improving urban air quality by reducing combustion- related pollution. One such program mandates the use of oxygenates in the wintertime to reduce CO emissions in cities such as Albuquerque,

A new method of analysis for S(IV) is described incorporating a counter-flow virtual impactor for collection and evaporation of cloud droplets with an SO2 analyzer. This technique allows analysis of aqueous S(IV) concentration in real-time and overco
