Non shunt liner

Because the sample retention time in the don't shunt liner, depends on the shape of the liner, gas velocity, the sample vaporization time, so don't usually shunt liner is designed to be straight, and cone type design, the samples gathered in the chromatographic column head, limit sample recoil, reduce the contact with the mouth metal sample. Add glass cotton liner can promote sample vaporization, and non-volatile residues, to prevent pollution. The chromatographic column used don't shunt liner is as follows:

All of the liner100%inertAll liners are of medium polarity Sexual deactivation, unless specifically requested

A straight pipeIt is recommended to use glass wool as it helps vaporize high molecular weight compounds and minimizes discriminationAdvantages:• economic

Disadvantages:• potential decomposition of active compounds such as iso-dieldrin and phenol after glass wool filling• easy to discriminate high molecular weight samples• the sample contacts the metal at the injection port

B taperAdvantages:• reduce the contact between the sample and the inlet metal• aggregate the sample to the chromatographic column

C concealed conical tube

Combined with the advantages of conical and biconical, the liner can be filled with glass wool. In addition, the liner can be double-column analyzed with a double-hole clamp sleeveAdvantages:• improved the efficiency of non-diversion• reduced decomposition of active compounds like isodieldrin and DDT• full vaporization?

Product Description

ERW welding round pipes also are called as Electric Resistance Welded Pipes.This type of steel pipes and tubes are widely used in various fields such as engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

While manufacturing ERW steel pipes, there are some strictly standard: high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.

• ERW welding steel pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved.

• Surface finish are available in black or bare, or with protective coatings.
