Its major activity is related to Gram-negative bacteria, and it is also capable of acting against Gram-negative bacilli resistant to the first- and second-generation cephalosporins (48). It is noted that the degradation results, in this case, in both methods (HPLC and turbidimetric) are approximately similar, as shown in Table4; however, this does not always happen. The method is depended upon the reaction of LOS-K with Silicotungestic acid in salt medium for the formation of a white precipitate. The. The alkaline and neutral conditions were heated to 40C. A spectrophotometer is used to determine turbidity ("cloudiness") by measuring the amount of light that passed through a suspension of cells. what are its advantages and disadvantages? There are several physical-chemical analytical methods for the quantification of ceftriaxone sodium, most of them are intended to quantify the drug in biological fluids, such a high-performance liquid chromatography (HPLC) (1821), ultra-performance liquid chromatography (UPLC) (2223), absorption spectroscopy ultravioleta (UV) (2, 24, 25), infrared spectroscopy (26), and spectrofluorimetry (27). 1. -H What are the advantages of turbidimetric method?

Although each method has advantages and disadvantages, all can be used to accurately and effectively determine the presence of endotoxins in various products. Quantitative research is an incredibly precise tool in the way that it only gathers cold hard figures. Turbidimetric determination is very helpful for plotting a standard growth curve; it allows us to easily track changes in growth phases without the hassle of counting plated colonies. disadvantages to templates. The solutions were prepared using deionized Milli Q water. Lack of microbiological quality control simultaneously with physical-chemical tests may contribute to bacterial resistance (1217).
