Nylander Prob

The Nylander test, also known as sulfur test, is a method for determining the sulfur content of metals and alloys. This method was developed by Swedish chemist Sven Wilhelm Henrik Nylander in 1871.

The Nylander method is based on the reaction between sulfur and copper in the presence of ferric chloride. This reaction produces copper sulfide, which is then analyzed. Copper sulfide has a bright yellow color, which makes it easy to determine its content in the alloy.

To carry out the analysis, it is necessary to prepare a solution containing ferric chloride and copper. A sample of the alloy is then added to this solution and analyzed for copper sulfide content. The amount of copper sulfide in the alloy is determined by the intensity of the yellow color of the solution.

The Nylander method is one of the most common methods for determining the sulfur content in metals. It is widely used in metallurgy to control product quality and prevent the release of harmful substances into the environment.



**Nylander Test** is a method for assessing blood quality based on the process of formation and destruction of red blood cells (erythrocytes). This method was invented by the Swedish scientist Sven Gunnar Nylander at the end of the 19th century and was one of the first methods of blood analysis. It is widely used in medical diagnostics and can detect blood diseases such as anemia, leukemia and others.

The general process of the Nylander test is that when an acid (ferric chloride) solution is added to the blood, the reaction produces positively charged iron-containing pigments, which then turn the sample red. The intensity of the color depends on the concentration of hemoglobin in the blood. The more hemoglobin, the darker the color of the sample.

The positive side of this test is that it is possible to more accurately determine the presence or absence of blood (thus, it is possible to establish its presence in the urine in different forms), while when using the Kano method it becomes impossible to determine the presence of carboxyhemoglobin in the urine (very important especially in case of carbonyl poisoning).

This is the advantage of the Nylandersky method over the Kano method. The disadvantage of the Naander test compared to the Ferdinand method is that it is slightly less accurate (you will need
