Their advantages and disadvantages by ( Banupriya et al for turbidimetric measurements of cell mass are! When analyzing your results after performing a serial dilution, you obtain an average of 40 colonies on your 1 x 106 plate. Method Turbidimetry is a simple, rapid method for following growth. The most important advantages of this method is the possibility to use plate readers connected to computers which enable automated reading; an error that occurs at a point of a wrong reading does not result in having to perform the whole analysis all over again. , Traple M.A., Okamoto R.T., Pinto T.J. (, Ali The mean percent content of sodium ceftriaxone calculated by both methods was 98.11% for HPLC and 98.94% for the turbidimetric method. Pharmaceutical industries widely use the HPLC method in their routine analysis, for this technique is able to separate the analyzed matrix from its degradation products and possible impurities, that is, it can be used for stability analysis. It presents efficacy against the enterobacteria Haemophilus influenza and Streptococcus pneumoniae, as well as Citrobacter, Serratiamarcescens, and Providencia. ).

Although these methods are statistically similar, there are differences between them that must be considered in each method. Turbidimetry. The standardization of the transmittance of the inoculums and absorbance readings were performed using spectrophotometer DU530 (Beckman Coulter, CA, USA). The range of detectable elements varies according to instrument configuration and set up, but typically EDXRF covers all elements from sodium (Na) to uranium (U), whilst WDXRF can extend this down to beryllium (Be). The turbidimetric test has the advantage of reducing this time to 4 h, providing optimization of the analysis, ease, and simplicity of the procedures, as well as the absence of the agar matrix, which could influence the diffusion of the drug for interaction with the microorganism ( 14, 15, 29-36 ).
