Some American-Made Chemical Reagents.

Desulfurization of Tabas Coals Using Chemical Reagents

Large reserves of coal in Tabas region of Iran are characterized by low ash and high caking index, suitable for use in metallurgy as coking coal. However, these coals cannot be gainfully utilized because of their high sulfur content. In this work, studies on desulfurization of Tabas coals were carried out in a batch reactor using various reagents. The most effective reagents,<...

Plant-made vaccines and reagents for the One Health initiative

The One Health initiative is increasingly becoming a prominent discussion topic in animal and human health, with its focus on prevention of spread of zoonotic diseases, both in animals, and from animals to humans. An important part of One Health is that diagnostics and vaccines for diseases may be the same thing - and be used for both humans and animals. One potential problem standing in the wa...

Economy and quality assessment of home made clinical chemistry reagents.

Most laboratories in Pakistan use expensive imported clinical chemistry reagent kits resulting in high cost/test to the patients. To reduce these costs, reagents were prepared from basic chemicals, substrates and enzymes imported from Sigma Chemical Company U.K. This reduced the cost/test by up to 500% in some reagents. The quality of these reagents was tested by Wellcome External, Q.C. Locally...

Selective Reagents for Chemical Ionization Mass Spectrometry

Much of the power of chemical ionization mass spectrometry stems from the finding that the characteristics of the Cl mass spectrum produced is dependent on both the nature of the reagent gas and the type of ion-molecule reaction used to ionize the sample. Different structural information can be obtained with different reagent gases. As a consequence, it is possible to control the type and quant...

There'll be some changes made.
