The kidney stone analysis can be done by, spectroscopy, X-ray diffraction, chemical analysis by semi-quantitative titrimetric
and calorimeter method, mass spectrometry and laser-induced breakdown spectroscopy, employed according to feasibility or resources.2,3 Recently, a study conducted in the Eastern Province of Saudi Arabia reported that the prevalence of calcium oxalate stones was 74.2%, uric acid stones 12.8% and mixed calcium oxalate/phosphate/uric acid stones 10.4%.4 The present study was aimed to analyze the chemical composition of urinary calculi in the Northern Border Region of Saudi Arabia and to propose recommendations for their prevention.
Total alkalinity was determined by titration with sulfuric acid using methyl orange and phenolphthalein as indicators, also chloride by silver nitrate titrimetric
method (Mhor M.).
Based on the calculations of the partial DS values of the acetyl portion among the three OH groups, we could determine the total DS value of the three CA samples obtained in this work in order to compare the values with the DS estimated by the titrimetric
method shown in Table 3.
It was determined by the 2,6-dichlorophenol indophenol (DCPI, Vetec) titrimetric
method (SILVA, 1999).
Hardness was measured by using EDTA titrimetric
The soil organic matter was determined by potassium bichromate titrimetric
method described in GB 9834-88:1988.
method used for qualitative determination of Esterase enzyme.
Free acidity was determined by the titrimetric
method; ten g of honey was dissolved in 75 ml distilled water, and this solution was titrated with 0.05 M NaOH solution until the pH reached 8.5.
These methods includes liquid chromatographic method with both capillary isotachophoresis and UV isotachophoresis, non-aqueous titrimetric
methods , fluorescence spectrophotometry , gas chromatography , high performance liquid chromatography , atomic absorption spectroscopy , reverse-phase high performance liquid chromatography  and so on.
Vitamin C Determination: This was determined using the 2,6-Dichloroindophenol Titrimetric
and spectrophotometric determination of doxycycline hyclate using bromate-bromide, methyl orange and indigo carmine," Chemical Industry and Chemical Engineering Quartely, vol.
When the extraction was equilibrated (about 20 min), 5 mL of raffinate and initial brine was withdrawn to analyze the content of boron by the alkaline titrimetric
method with an uncertainty of [less than or equal to] [+ or -] 0.3% in mass .
