2 11 Sample pretreatment, Accessories Material properties of products Stainless (SUS-316) A general-purpose material for general HPLC products. Contains Ni, Cr, Mo, etc, as well as Fe, and is highly resistant to corrosion. Polyacetal An engineering plastic. A polymer in which aldehyde compounds are polymerized, with excellent chemical resistance and excellent machinability. PEEK (polyetheretherketone) A super engineering plastic developed as an alternative to metals. A polymer containing ketones and ether bonds, it is highly resistant to pressure, chemicals, heat, and fatigue. Used as an alternative to stainless for a metal-free tubing system. Polypropylene A polymer of propylene. Excellent chemical and heat resistance. Often used for containers since processing, such as injection molding, is easy. Teflon (polytetrafluoroethylene, PTFE) A polymer of tetrafluoroethylene. Highly resistant to chemicals but not so resistant to pressure as PEEK. Generally used for low pressure tubing systems.

3 Column protection Stainless steel precolumn filters are convenient for the case shown below: One of the causes of a gradual increase of a column pressure after each sample injection is that fine particles in the sample clog the frit of the column. Replacing the column frit is one solution; however it is more convenient to use precolumn filter. Connect a precolumn filter between the injector and the column, check the line pressure occasionally, and replace the precolumn filter when the line pressure increases. Stainless steel precolumn filters are suitable for stainless steel tubing systems. Both PEEK and stainless steel precolumn filters are suitable for PEEK tubing systems. Problem prevention High-molecular weight compounds (proteins, DNA, sugars, etc.) that easily and irreversibly adsorb to the main column are likely to cause a pressure increase and separation failure. When these compounds adsorb to the main column, it is difficult to recover column performance by cleaning. A guard column will protect the main column when fouling of the main column is due to contamination from sample matrices. YMC-Pack YMC guard cartridges Precolumn filter Stainless steel precolumn filter Filter construction with minimal dead volume Effective diameter of the filter is extremely small about 1.6 mm. Sample diffusion that occurs in passage is minimized.

6 11 Tubing parts Universal connector Enables perfect column connectivity A movable ferrule and a fixing screw enable secure connection to the column endfitting. There is no cavity at the top of the ferrule. Super high-pressure resistance Universal connectors are high performance connectors resistant to high pressure up to 70 MPa when tightened only by hand. For connection to a guard column The double type is the most suitable for connecting of a main column and a guard column. Double type Single type Fixing screw Fixing ferrule Quick, easy and secure connection. No tools required. Adjuster screw Sealing ferrule (replacable) Tightening the fixing screw forces a tube to squeeze into the column as far as it will go, and the tube makes tight contact with the screw hole. The tube makes tight contact with the screw hole by tightening a fixing screw.

Metal free The ferrule at the wetted part of the connector is made from PEEK. Handy connector 2 is suitable for metal-free tubing systems using PEEK tubes. Ferrule is replaceable Only the ferrule needs to be replaced when it deteriorates, as opposed to the entire connector. Handy connector 2 XRP0204 For tubing system of 1/16 outer diameter, 2-pack XRP0205 Spare PEEK ferrule, 10-pack Be aware that Handy connector 2 cannot be connected to Old Shimadzu type, Old JASCO type, or Old Hitachi type tubes.

(4) Be sure that there is no leak from the screw hole. (1) Extend the top of PEEK tube beyond the ferrule. (2) Force the tube to make tight contact with the bottom of the screw hole. 149

8 11 PEEK tubing Easy to use PEEK tubing is made from a material that is flexible and easy to use. It is easily cut using a commercially available cutting knife. A PEEK tube with an inner diameter of mm is useable at up to 40 MPa. PEEK tubes are practical general tubing as alternatives to stainless steel tubing. They are suitable for metal-free tubing systems. A Handy connector is suitable for connection of PEEK tubing to a column.

Some effort is needed to minimize the dead volume in a tubing system among the injector column and detector, in order to prevent poor peak shape. Using a tube with a small inner diameter (0.127 mm) is one solution. When a tube is connected to a union or a column, it is important to give due consideration to make the top of the tube contact flush with the bottom of the screw hole and to avoid leakage or creation of a cavity.

14 11 Pressure resistant empty glass columns Suitable for preparative chromatography Pressure resistant empty glass columns are useful for early purification of natural products, after-treatment of open column chromatography and pre-treatment of preparative HPLC. They are also suitable for removal of impure compounds produced during organic synthesis. The most suitable for self-packing Low-cost preparative isolation can be achieved by self-packing. Pressure resistant empty glass columns are highly flexible tools for preparative isolation because many types of packing materials may be packed into the column. Pressure resistance YMC empty glass columns, made from Pyrex glass, have excellent pressure resistance. They are suitable for spherical and irregular packing materials with a particle size of 50 μm or more. Applicable to medium-pressure and high-performance liquid chromatography systems Pressure resistant empty glass columns can be connected to existing chromatographs, making the preparative isolation easy. Metal free column No metal is used for wetted parts. There is no danger of corrosion caused by acids or of metal contamination in isolation fractions. Pressure resistant empty glass columns are suitable for a metalfree HPLC system. Visibility In contrast to stainless steel columns, the separation behavior of samples analyzed by chromatography can be observed visually. It is useful for preparative isolation or removal of colored material.
