Results from light obscuration (a-b) and turbidimetric measurements (c-d) on two different precipitation reactions. a increasing number of particles larger than 0.5 μm per ml as the pH of TPNaq increases from addition of 0.1 M NaOH (n > 3). The first column represents TPNaq without added NaOH; b particles larger than 0.5 μm per ml in samples of TPNaq and Acyclovir (1 + 1) at different time points after mixing (n = 3); c increasing turbidity with increasing pH of TPNaq (n = 2). The first column represents TPNaq without added NaOH; d turbidity in samples with TPNaq and Acyclovir (1 + 1) at different time points after mixing (n = 3)
