MetaGuard™ are stand-alone, disposable columns which connect directly into the end-fitting of any manufacturer’s analytical column, providing outstanding column protection and unparalleled convenience. The single-piece design of MetaGuard is a major advance over other direct-connect guards which have multiple, hard-to-handle and easy-to-lose pieces. With a twist of wrist MetaGuard forms a fingertight, very low dead-volume connection which minimizes sample dispersion, maximizes system efficiency, and is leak-free to over 5000 psi! MetaGuard has no appreciable effect on column efficiency or peak shape. The compact design of MetaGuard makes it perfect for use in column-heating applications where space considerations are crucial. MetaGuard columns are available filled with a wide variety of name-brand packings, ensuring that the guard packing exactly matches the packing in the analytical column. MetaGuard columns are compatible with all manufacturers' columns.

The SafeGuard system is comprised of disposable cartridges used in combination with a durable, reusable holder. SafeGuard is connected to the analytical column with a short capillary tubing “coupler.” The SafeGuard system is designed to minimize dead volume and will not decrease the efficiency or resolution of the HPLC system. The holder is machined with a microbore-aperture and flow path which has virtually zero dead volume. The cartridges add only 1cm of bed depth to the system and have negligible effect on retention and system pressure. The reusable SafeGuard holder is made of high quality stainless steel with a metal-free, PEEK-lined flowpath. Each holder is supplied with two polymeric fingertight fittings.

SafeGuard cartridges are available with a huge variety of different column packings and are compatible with all manufacturer’s HPLC columns. SafeGuard cartridges are also very popular for on-line trace enrichment and sample preparation in column switching applications.
