Summary
The copper sulphate method is a reliable and cost-effective tool for hemoglobin screening in mass health programs. It shows high correlation with automated methods, especially for healthy individuals.
Area of Science:
- Hematology
- Clinical Chemistry
- Public Health Screening
Background:
- Accurate hemoglobin measurement is crucial for diagnosing anemia and monitoring public health.
- Existing methods for hemoglobin screening can be costly or complex for large-scale application.
Purpose of the Study:
- To evaluate the reliability and cost-effectiveness of the copper sulphate method for hemoglobin screening.
- To compare the copper sulphate method with automated colorimetric methods.
Main Methods:
- Automated colorimetric and copper sulphate methods were employed.
- 218 blood specimens were analyzed using both techniques.
Main Results:
- A high correlation (r = 0.82) was observed between the copper sulphate and automated colorimetric methods.
- The copper sulphate method demonstrated superior performance in the higher hemoglobin range, relevant for healthy populations.
- The method showed a tendency for lower results in the lower hemoglobin range compared to cyanmethaemoglobin.
Conclusions:
- The copper sulphate method is a reliable and accurate screening tool for hemoglobin.
- Its cost-effectiveness makes it highly suitable for mass hemoglobin screening programs.
- The method is particularly advantageous for assessing hemoglobin levels in healthy individuals.

04:08Determining the pH of Salt Solutions
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution. In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...
01:03Precipitation Gravimetry
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
