Wide Usage of Gold Testing Machine

Gold has been one of the most precious metals for over a million years. It is combined with other metals to make jewellery of different varieties. There are many ways to test the purity of gold. Since gold is a precious metal it is often found alloyed and mixed with other metals. So it is pertinent to test the purity of the metal. The gold testing machine is used mainly for this purpose.

Ways to Test the Purity of Gold
Different methods are adopted to test the purity of gold. Karat is the measurement used for measuring the purity of gold. Pure gold is usually known as 24 karat gold. Before the invention of gold testing machine, the purity of gold was tested using porcelain, glass and magnet. The use of porcelain to test the purity of the metal-gold included scratching the sample metal on unglazed porcelain, if the color of the streak is yellow, it is pure gold.

Similarly the use of glass to check the purity of gold included scratching the sample metal on a piece of glass, since gold is known to be softer than glass, it should not leave any mark on the glass when scratched.

Magnets were also considered as the ancient gold testing machine. This simple test involves holding the sample metal near to the magnet, if it is pure gold, the magnet fails to attract it. All these tests mentioned above are different kinds of initial tests which do not prove the content of gold present or the exact amount. Since the gold testing machine was unavailable in those days, most of the people resorted to such methods which have become obsolete today.Acid testing is another method to test the purity of gold. But it is known to cause damage to the precious metal so it is not used by most of the professionals though it is quiet cheap compared to other methods of testing the purity of gold.

Advent of Gold Testing Machine
With the growing usage of machines in every field, the gold market witnessed the advent of innovatory machines that were capable of testing the purity of gold. There are a wide variety of machines that are used for testing gold.

There are electronic gold testers that can be used quite efficiently anywhere and anytime. This gold testing machine can be used in offices, homes and jewellery shops too. As these machines are used widely in different places to separate and identify fake gold, there are a number of gold testing machine manufacturers listed in the b2b markets.

The Elvax is a popular gold testing machine that is guaranteed to provide accurate measurement of the metal. It is an Energy Dispersive X-Ray Fluorescence analyser, also known as EDXRF. It can be used in industries, research purposes and for analyzing jewellery.

Scientific Instrument Supplier Anticipating Better Growth

For the resolving powers of our scientific instruments decide, at a given moment, of the size and the vision of our Universe, and of the image we then make of ourselves. – Albert Claude

Introduction

Wiki defines a scientific instrument as any type of equipment, machine or device which is specifically designed or constructed ingeniously refined to apply utmost efficiency in the utilization of some well proven physical principle, relationship or technology to facilitate the pursuit, acquisition and storage of repeatable, and verifiable data.

As India is growing by leaps and bounds in the science and technology sector, the demand for the scientific instruments is experiencing an overall increase . During the downturn the single most affected sector was R&D as many thought it was something which can be put on hold till the recession gets over. Quite naturally the demand for such instruments came down . Now as the economy is heading towards recovery, this sector is also getting the much needed push.

Scientific instruments are usually a part of laboratory equipments, but are considered more sophisticated and more specialized than other measuring instruments as scales, meter sticks, chronometers etc.

Chinese Scenario

Industry observers feels that the scientific instrumentation industry has a huge market potential in china. As per the the last available statistics the chinese scientific instrumentation industry is estimated to reach 100 billion Yuan by the end of 2010. China’s growth projection is being attributed to steady economic growth, investments into R& D with a long term vision and favourable business environment.

Currently, china is mostly into low-grade equipment production, however, soon high-end equipment production could take the centre stage. The general notion is that the high end production is taken care by the US based multinationals and a conscious effort is being made to encourage chinese companies to venture out in this segment.

India’s challenges

Even though there have been long talks about laying the emphasis on the research and development in India, not much has been done in practise. On top of that, the talent poaching by the western countries and the multi nationals in India is depriving the country of its most valuable asset. Many scientific instrument suppliers echo the fact that the Indian govt. needs to look into this with utmost priority.

Scientific instrument suppliers further add that in today’s highly competitive market conditions, the lack of healthy competition within the industry norms, constraints on the profit margins has further complicated their problems. The only silver lining in the cloud is – the positive economic forecast for the Indian market. Needless to say, the scientific instrument suppliers are anticipating better times ahead !
