2008-05-15Black Diamond - God's Gift - [Jewellery Identification]
Diamonds, has become a high society one of the most popular decorations. In various colors of diamonds, diamonds and more scarce and their number is particularly valuable. Black Diamond in the end from which direction, why would so precious? »
In December 30, 2006 published in the <<astrophysics communications magazine>>, from Florida International University's Jozsef Garai and Stephen Haggerty, and Kai Sixi Reserve University Sandeep Rekhi and Mark Chance said that they found it Of a black diamond (also known as the Black Diamond do) outside the origin of the Earth. As early as the birth of the Earth has not yet time, black diamonds may have existed in the universe, scientists found in Black Diamond in a lot of hydrogen elements, indicating that it came from Elements of the hydrogen-rich outer space. -
2008-05-15Identification of pearls - [Jewellery Identification]
Natural pearls are cultured pearls and pearl of the points, cultured pearls have seawater and freshwater-of-hours. Natural pearl production less expensive prices, and large quantities can be cultured pearl output, the price is much lower. The main difference between the two is that natural pearls and cultured pearls are not nuclear. The core of natural pearls are just some sand or parasites, and so on, not even nuclear. -
2008-05-15Identification of opal - [Jewellery Identification]
Opal according to its color can be divided into black opal, white opal, yellow opal, and so on, with the highest black opal prices. In order to lower the price of white or yellow opal improve grades, some people use artificial methods to change color and become "black opal" to seek Gregory. The main way is to cook with sugar or injected plastic, black to white opal. Identification method is to cook the sugar or injection of opal significantly different proportions, in water testing, the proportion of the value of its variable light. Heating can also be used after the test injection needles opal, natural opal fever needlestick not into, injection opal can Zhajin and produce plastic Yang of the odour. -

As a precious jewel on the market over three kt above the natural ruby is very rare, if encountered larger block of Ruby, it is necessary to draw attention, because natural than man-made ruby ruby hundreds of times higher than the value, a slightly negligence, will "eat Medicine. " -
2008-05-15The identification of diamonds - [Diamonds Identification]
Diamond is the hardest natural material in the material, diamonds can be described any other precious stones, but none described any other gem diamonds fixed. Can also use the "standard hardness" characterization, a hardness of less than 9 degrees, are fake diamonds. Diamond also has a hydrophobic, such as pens in the diamond surface to draw a line, into one continuous line, and other precious stones, was intermittently interrupted the line. These methods in the identification of diamonds in a certain reference value. Can also observe the magnifying glass 10 times, 10 times under the magnifying glass, most of the diamond-Xia visible defects, the growth triangle pattern, the diamond surface, "red, orange, blue" colored "Fire" light. Full light. The most accurate and reliable way is to use "thermal conductivity instrument", measured thermal data to distinguish between genuine and fake diamonds, but "thermal conductivity for" price more expensive. -

Domestically, water is traditionally heated in vessels known as kettles , cauldrons , pots or coppers . These vessels heat a batch of water but do not produce a continual supply. Appliances for providing a more-or-less constant supply of hot water are variously known as water heaters , boilers , heat exchangers , calorifiers or geysers depending on whether they are heating Potable or non-potable water, in domestic or industrial use, their energy source, and in which part of the world they are found. In domestic installations, potable water heated for uses other than space heating is sometimes known as Domestic Hot Water ( DHW ).

2008-05-08Introduction Stack Analyzers - [Industrial Analyzer]
Increasing regulatory pressure has produced great interest in monitoring for hydrogen chloride (HCl) and chlorine (Cl2) in stacks and from other sources. Measurement of these gases has important process control implications as well. Traditional spectroscopic methods have been used in these applications, but have not always been found to be satisfactory. This paper describes the use of IMS in performing these measurements. This technique is shown to have distinct advantages over competing techniques. Both compounds can be measured in a single instrument, limits of detection are in the area of 0.5 ppb, and no interference is found at high humidity levels. Theory of operation, hardware design, sensitivity and specificity will be discussed.
Introduction Stack Analyzers
HCl and Cl2 are used or produced in a wide variety of chemical processes. They may also be
