Purge and Trap System (described on

the previous page) and the S.I.S. GLT thermal desorp-

tion tubes. In addition, optional fittings are available to adapt the
purging heads for use with other manufacturers desorption or
sampling tubes. Two styles of the Stainless Steel Purging Heads
are available. The top fitting of both purge heads consists of a
1/16" fitting for the attachment of the sparging needle followed by
needle adapter to seal the needle in place and provide for the
attachment of the purging gas line. The side gas line is for the
use of a dry purge gas to aid in removing water from the desorp-
tion tube adsorbents or samples. When not required, this fitting
is capped with the 1/16" plug cap provided. The desorption tubes
are screwed into the end of the Stainless Steel Purging Head and
leak tight seals are made with the standard 1/4" PTFE washers.

The Standard Purging Head is the system that is supplied

with the Complete Purge and Trap System described previously.
The bottom fitting consists of a 1/2" Swagelok

™

fitting with PTFE

ferrules for the attachment of standard 1/2" diameter sample
tubes. An optional 12 mm Swagelok nut and 12 mm PTFE fer-
rule can be used with this fitting to adapt it for use with standard
12 mm sample tubes such as the disposable 12 mm tubes read-
ily available from many suppliers.

The Tube Style Purging Head contains of a 1/4" outside diam-

eter tube instead of the 1/2" fitting described above. This permits
the use of other sampling tubes which the user can easily adapt
to this fitting via standard 1/4" GC fittings, such as the 1/4" to 1/2"
union included with this purge head.

Two optional adapters screw into the purge head outlet to

adapt both of the purging heads for other manufacturers sam-
pling tubes. The 1/4" Tube Adapter (783007 Part #783007--Click to order

SIS Newsletter

Covers SIS products, services, promotions, news, and other mass spectrometer related information.

28 Aug 2013: Nanoliter Dispensing Devices can be used to place media on the MALDI plates for MALDI/TOF instruments, but the most exciting ability of this device is to collimate droplets directly into the ion source like electrospray (ESI), the unique concept being that nearly 100% of the droplets go directly into the source versus <1% from ESI, giving a huge increase in sensitivity. We believe this could be the next big advance in LC/MS sources. [NEW]
