Which method is known as micro qualitative analysis?

The most known methods used in microanalysis include: Most of the spectroscopy methods: ultraviolet–visible spectroscopy, infrared spectroscopy, nuclear magnetic resonance, X-ray fluorescence, Energy-dispersive X-ray spectroscopy, Wavelength-dispersive X-ray spectroscopy, and mass spectrometry.

What is semi micro scale?

The MS Semi-micro analytical balances from METTLER TOLEDO are part of the MS product line and consist of a range of laboratory or lab balances offering a readability of 0.1 mg – 0.01 mg (4-5 decimal places) and a capacity between 100 and 200 g.

What is group reagent?

The reagent which is employed in idntifying a gourp of radicals is known as group reagent . Ammonium sulphide is used for testing 5th group cations. Sodium hydroxide is the group reagent for the zero group.

What are the advantages of semi micro analysis?

Advantages: Semi-micro analysis is very normal and less expensive. And in micro analysis the amount of analyze is very small, the amount of produced wastage is very small- so the environment remain clean.

What are group 3 reagents?

The group reagent of 3 rd group is ammonium sulphide solution or hydrogen sulphide gas in the presence of ammonia and ammonium chloride .

What are the group 5 cations?

Group 5 cations are magnesium (II) Mg2+, potassium (I) K+ and sodium (I) Na+. These cations do not react with hydrochloric acid HCl, hydrogen sulphide H2S, ammonium sulphide and ammonium carbonate (NH4)2CO3.

What is semi micro technique?

Semi micro analysis is the analysis of substances with a mass in the micro-scale. Usually, the sample of this type of analysis has 100-500mg mass and 1.0mL volume. Since these techniques work with very small sample amounts, it is necessary to avoid any contaminations.
