In the past, there was a remark that the rosewood was extinct, and there were some misunderstandings and disputes about the recognition of red sandalwood. In fact, the real rosewood has not only disappeared, but has been continuously entering the country. This is an indisputable fact in the wood industry and the collection industry. The "red sandalism" is actually related to the interests of the rosewood furniture business. According to statistics from relevant experts, the total amount of rosewood imported from China from 1988 to 2003 was 3730MT. Rosewood is mainly produced in southern and southwestern India.
The characteristics of rosewood are that the growth is not obvious, the new cut of the heartwood is orange-red, and the long-term turn is dark purple or black purple, often with light and purple stripes; the brown eyes are thin and dense, like a cow's hair, called the cow's hair, will be long Produce horny luster, observe the red sandalwood from some angles, and have a satin-like glare. The red sandalwood is more important than the similar redwood, sinking into the water; the aroma is not or very weak; the rosewood is stable, not cracked, not easy to engrave...!
However, due to the world's preference for red sandalwood, many other types of wood are mixed, and the most prominent is the African madagascar Lushi black Dalbergia (commonly known as "big leaf rosewood") posing as Indian lobular rosewood. In fact, the Indian lobular rosewood is very characteristic, and the main distinction between the two is as follows:
1, aroma
Indian lobular rosewood: no or fragrant scent
Lushi Black Dalbergia: Sour Scent
2, weight
Indian lobular rosewood: sinking in water
Lushi Black Dalbergia: sinking in water, the proportion of <1 is floating in water
3, board surface color
Indian lobular rosewood: purple or burgundy
Lushi Black Dalbergia: The new opening is orange-red, and after a long time it is dark purple or the bottom color is black.
4, fluorescence reflection
Indian lobular rosewood: yes
Lushi Black Dalbergia: None
5, catheter
Indian lobular rosewood: filled with red gum and rosewood
L. black sandalwood: the color of the catheter line is dark, contrasting with the true color
6, oily texture
Indian lobular rosewood: strong
Lushi Black Dalbergia: Strong, lighter than poor
7, texture
Indian lobular rosewood: texture straight, less pattern
L. black sandalwood: obvious pattern, partial curl
Nanomicro Tech offers a series of hydrophobic interaction chromatography (HIC) media for high efficiency separation and purification of proteins and peptides. HIC is used to separate proteins on the basis of relative hydrophobicity. The unique feature of HIC is that proteins bind at high salt concentration and elute at low salt concentration. While in reversed phase column chromatography (RPC), desorption is often promoted by the addition of an increasing amount of organic solvent. Therefore gentle binding and elution condition of HIC allows a better retaining of the biologic activity of the target protein than RPC in which organic solvents are applied. The strength of the hydrophobic interaction is influenced strongly by the nature of the salt components in the mobile phase. The salt concentration needed depends on the protein hydrophobicity and solubility. HIC is particularly attractive for Protein Purification after ion exchange and affinity chromatography, where the sample with high salt concentration can often be applied directly to HIC. By combining HIC with ion exchange or affinity chromatography, the purification of biomolecules can be completed efficiently.
