Development of a portable, simple and inexpensive equipment with adequate sensitivity for turbidimetric and/or nephelometric sequential analyses practically simultaneous is the aim of this study. In fact, in-situ and on-line analysis of chemical substances of interest (analytes) can be accomplished. This is requested mainly in situations in which the place is difficult to access or even in circumstances in which the physical- chemical characteristics of the samples should be unchanged. Thus, the equipment was applied in- situ sulfate determination in lake samples. Analytes of interest such as N-acetylcysteine, captopril and thiamine in pharmaceutical samples and potassium in isotonic beverages were also analyzed with the developed instrumen...
