Thermo Scientific TRACE TR-Pesticide (PN 26RF142F)
30 m x 0.25 mm ID x 0.25 μm film with 5 m integrated guard column
Tip Use the integrated guard column in the MS transfer line. The empty guard column in the transfer lines keeps the
background low and guarantees optimum chromatographic integrity.
1 m x 0.53 mm ID (optional) for easy exchange with dirty matrix samples
For matrix samples (e.g. from QuEChERS sample prep), use an empty pre-column of Siltec deactivated silica tubing
(PN 260G401P).
Connectors SilTite Mini-Unions (PN 073550)
Tip Mini-unions of low thermal mass are a durable and easy to handle connection. Check for leaks regularly if glass quick fit
pieces are used.
