CARTRIDGE GUARD COLUMNS - 100% Biocompatible Flow Path /Economical Cartridge with Titanium Frits / Reusable Holder Complete with Fingertight Fittings |
QUICK
RELEASE ™ CARTRIDGE GUARD COLUMN SYSTEM Changing Guard Column Cartridges was Never this Easy! / 100% Biocompatible Flow Path |
||
Insert one of these Upchurch Scientific® analytical guard columns between the injection valve and column of your HPLC system to extend the life of your column and help ensure reproducible results. Convenient, prepacked PEEK™ polymer cartridges complete the system and are available in a variety of bonded phases to match your column chemistry. Each cartridge is slurry packed with 5µm or 10µm base-deactivated 80A spherical silica, resulting in a much higher quality product than can be achieved through dry packing. Our C-270 Stainless Steel Guard Column Holder is engineered for high pressure applications to 4,000 psi (276 bar). We surface treat each of these holders to prevent galling (1), a potential problem with threaded metal parts. The Tefzel® C-283 Holder is designed for low pressure systems (<_1,000 psi [69 bar]), such as DNA sequencers. | The
simple design of our patented Quick Release Guard Cartridges and Streamline Cartridge Holder makes installing and changing guard columns quick and easy. Simply thread one end of the Direct Connect Adapter (included) into the end of your column and the other end into the C-600 Cartridge Holder. Insert a Quick Release Guard Cartridge into the holder. Then use the supplied F-130 Fingertight Fitting with your 1/16" OD tubing to create a Zero Dead Volume (ZDV) connection. |

The
flow paths of both the C-270 and C-283 Guard Column Holders are
biocompatible. Each comes complete with fittings for 1/16" OD
tubing, and can be used with any of the C-28X or C-7XX guard column
cartridges listed on this page. (1) Galling is a form of cold welding, When two fittings manufactured from the same metal are wrench-tightened too tightly, they can weld together. |
This system is pressure rated to 6,000 psi (414 bar). All material in contact with the mobile phase is constructed of 100% biocompatible PEEK polymer including the frits. The Quick Release Guard Cartridges are packed with C18 high-carbon load 5µm base-deactivated 80A spherical silica. |

This Upchurch Scientific® ultralow volume guard column is ideal for narrow-bore chromatography. The total packing volume of 16.2µL ensures maximum column efficiency and analytical column protection. The column can be easily dry packed using the specially designed funnel (C-128-20). A 3g bottle of our packing material will pack this column more than 120 times. Frits often become plugged before a guard column is contaminated. The two 0.5µm frits included with this guard column can be changed in minutes. Optional 2µm frits may be purchased separately (C-408). | The C-130B is our most popular guard column. HPLC users find this column easy to pack and extremely economical. This narrow-bore short column creates only a slight pressure increase with no detectable theoretical plate loss when used with a 3mm ID or larger column. The 2µm frits are easy to change, prolonging the life of the guard column. With only 62µL packing volume per guard column, a 3g bottle of packing material will pack about 30 guard columns.For convenience, we offer the C-135B kit. With two guard columns, there is always a back-up available to help eliminate downtime. |

COLUMN
COUPLERS - Low Swept-Volume Connections / Inexpensive |
||||
Upon
request, Upchurch Scientific® designed the 10mm ID x 1cm column. Total
internal volume is just 780µL, which only requires approximately 1.50g
of packing material - typically the same material used in your semi-prep
column. The cartridge is easily dry packed, and the frit caps thread
over the 1/2" OD body tube. When the packing material needs to be replaced, the cartridge is easily disassembled, cleaned and repacked - all within minutes. The C-1000 Holder will hold to high pressures, and is specially treated to prevent galling.(1) Use standard 10-32 coned fittings (not included) to connect your 1/16" OD tubing. (1)Galling is a form of "cold welding" When two fittings manufactured from the same metal are wrench-tightened too tightly, they can weld together |
These
universal column couplers permit a very low swept-volume connection(1),
with zero loss in column efficiency. These couplers will connect any
column with 10-32 internal threads to a precolumn or guard column with
the same threads. They may also be used to join two columns in series.
All three couplers consist of two Fingertight fittings and a short
length of 1/16" OD tubing. (1) Swept Volumes (total tubing volume): U-283 = 1.3µL U-284 = 1.3µL U-287 = 3.6µL |
