What are the pharmaceutical applications of gravimetric analysis?

Answer 1

Specific gravity is relating of the density of an object to the density of water. In a pharmacy setting specific gravity becomes important when measuring the amount of a powder to the amount of water.

Answer 2

A gravimetric method used for the determination of diclofenac in pharmaceutical preparations was developed.

Used in the measurement of the essential elements in plant-based herbal drugs and foods.

Used in the estimation of the pollutants in the air.

Example: SO2.

Used in the estimation of the SO2 in the soft drinks.

Used in the calibration instruments.

Example: Balances calibration

Used in the estimation of the chloride ion in the water supplies.

Answer 3

for every elements, there is a unique specific gravity. and as we know pharma cos use many elements to make a particular drug. so the drug also has got a particular unique specific gravity. one can identify if the drug is pure in its form or any impurities are there , just by finding the specific gravity.

Answer 4

Practical Specific Gravity UsesSpecific gravity measurements can be used in a wide variety of industries. It is particularly useful because it allows access to molecular information in a non-invasive way.

Gem Purity: The purity of a gem can be determined by comparing its specific gravity with the patron number (measured over a gem with high purity level). This allows the gem's value to be determined very quickly.

Eggshell thickness: Eggshell thickness is an important factor in the poultry industry. It decays with the age of the hen or under adverse conditions. If the thickness falls below certain expected values, the eggs are not marketable. The eggshell mainly determines an egg's specific gravity, while the other components have specific gravity close to 1 (one) (shell= 2.325; yolk= 1.032; albumen= 1.038; shell membranes= 1.075). One can gain a good idea of the shell's state by measuring the whole egg's specific gravity.

Soil's Compressive strength: Engineers need to know a soil's compressive strength to choose a construction method (among other things). Specific gravity and compressibility are highly connected and can be obtained one from the other.

Oil Industry: Crude oil and its refined products are normally measured either by volume in gallons and US barrels or by weight in tons. Specific gravity or density can measure the relationship between volume and weight. The specific gravity is related with the 'degree API,' a measurement of the oil's inherent power (regular, super, etc.).

Answer 5

If a substance has a lower specific gravity than another substance, it will float on that fluid. Specific gravity is also used to identify substances if pure. Specific gravity can also be used to determine similar gems, to check the progress of reactions and concentrations of solutions, and to test battery fluid and antifreeze.

Answer 6

Specific gravity is the same concept as mass, when applied to a liquid.

Answer 7

specific gravity is used in pharmacy.

Answer 8

It keeps you on the ground.

Answer 9

Measuring the amount of fats in foods.

Answer 10

This is a method of chemical analysis.
