MSD Conversion Fitting
• A flat, soft aluminum sealing ring deforms and butt-seals against the MSD interface.
• A standard Vespel® ferrule seals the column and 1 /16-inch stainless steel nut.
• Fitting is constructed of nickel-plated brass for longevity and softness.
• Use any standard Vespel® or Vespel ®/graphite 1/16-inch ferrule.
• Includes a 1/ 16-inch stainless steel nut and two replacement sealing rings. Order ferrules separately.
The butt-seal in Agilent’s MSD interface also seals the MSD source to the
capillary column. This system is prone to leakage. Restek’s MSD conver-
sion fitting is designed with two separate seals to reduce the chance of
leaks: a crunch washer seals the MSD conversion fitting to the source,
and a ferrule seals the capillary tubing to the conversion fitting.

MSD Source Nut
The nut bore has been changed from 0.8mm to 1.2mm to permit easy removal
of ferrules with a standard tapered-needle file (cat.# 20106). The nuts match
the manufacturer’s original part specifications and are made of brass to pre-
vent thread-stripping on the transfer line.
(Similar to Agilent part # 05988-20066.)

Install the nut and ferrule
onto the column, then
insert the column through
the installation tool, expos-
ing several centimeters at
the exit end.
Tighten the nut. Score and remove the
exposed end of the col-
umn making sure of a
clean, square cut, then
loosen the nut.
The ferrule will be
properly seated and
should remain in place
when light force is
applied. Install the col-
umn into the GC/MS
interface.

Pumps, Oil Vacuum Pump
• Formulated from crude oil stocks
known for durability and line lubri-
cating qualities.
• Use in Agilent 5973/5972/5971/ and
GCD mass spec systems, or in other
manufacturers’ MSD systems that
require rough pump oil.
• Replace oil in the foreline rough
pump every six months (average
use).

Ion Source Cleaning Powder
• Use to clean the ion source when
you encounter poor sensitivity and
inadequate abundances at high
masses.
• Clean surfaces that contact the sam-
ple or ion beam with a slurry of this
powder and reagent-grade
methanol on a cotton swab, or an
abrasive paper.
