Click to Quickly Translate Methods
and Calculate Flows
Fresh from winning a 2014
TASIA (The Analytical Scientist
Innovation Awards), the new
EZGC® method translator and
flow calculator makes it sim-
ple to switch carrier gases, to
change column dimensions
or detectors, or to optimize a
method for greater efficiency
and shorter analysis times. Simply enter your original method speci-
fications to receive a full set of translation conditions that provide
similar chromatography. Results include oven program and run time
as well as average velocity, flow rate, splitless valve time, and other
parameters—all in an easy-to-use, single-screen interface.
Available for online use or download, these free tools are the lat-
est addition to the EZGC® method development suite, already well
known for the analyst-favorite EZGC® chromatogram modeler.
Save yourself hours of calculations, guesswork, and trial-and-error:
Make the award-winning EZGC® suite your go-to resource for
method development.

Get Raptor™ Speed, Efficiency, and
Ruggedness in 2.7 and 5 µm C18
Raptor™ LC columns launchedwith the time-tested Restek® Biphenyl
and the acid-resistant ARC-18 phases on 2.7 µm particles. Now, this
new species of column has grown to include 5 µm particles and a
general-purpose C18 phase.
Every LC lab has a cache of C18s, but while the chemistry may
be similar, every C18 is not created equal. The traditional end-
capped Raptor™ C18 offers the highest hydrophobic retention of
any Raptor™ phase, and it is compatible with a wide range of mobile
phases (pH 2–8). This new phase offers consistently excellent data
quality in less time acrossmyriad reversed-phase applications, matri-
ces, and compound classes. When you need a general-purpose LC
column, don’t just grab any C18. Choose the speed, efficiency, and
long-lasting ruggedness of the new Raptor™ C18 SPP LC column.
Like the C18, all Raptor™ phases are now available on both 2.7
and 5 µm particles. Raptor™ 5 μm particles provide the benefits of
SPP without the significant increase in pressure. Their improved
efficiency and sensitivity help you easily and significantly speed
up existing methods on systems that
simply cannot handle smaller 2.7 μm
core-shell particles. To increase sample
throughput and productivity on your
existing 400-bar HPLC system, 5 μm
Raptor™ columns are a perfect choice.
(See page 6 for more information
on choosing between 2.7 and 5 µm
Raptor™ particles.)

GC-MS/MS is the technique of choice for analyzing pesticide resi-
dues in many fruits, vegetables, botanicals, and herbals like tea,
ginseng, ginger, Echinacea, and dietary supplements. And Restek's
new GC-MS/MS pesticide reference standards kit contains over two
hundred compounds pulled from the food safety lists of the FDA,
USDA, and other global agencies.
This stock, comprehensive set joins the 204-compound LC-MS/MS kit
in Restek's lineup of world-class certified reference materials (CRMs)
for multiresidue pesticide analysis. Formulated and quantitatively
tested for maximum long-term stability, both kits feature detailed
support documentation and a free optimized method; the down-
loadable XLS files include conditions and transition tables.
No more long nights or weekends in the lab. No more custom stan-
dards. Restek's food safety chemists can help you make quick work of
getting the accurate results you need.
Rxi®-1301Sil MS GC Columns
Provide the Selectivity you
need without the Bleed
Cyano stationary phases provide more retention of
polar compounds than 5-type columns; however,
they are prone to high bleed and poor robustness.
New Rxi®-1301Sil MS GC columns from Restek offer true cyano phase
selectivity along with the highest thermal stability in the indus-
try, which ensures you get dependable, accurate MS results and
increased uptime.
In addition to providing both stable 1301 selectivity and the low-
est bleed/highest temperature limits available, the Rxi®-1301Sil MS
column is designed to provide maximum inertness. Each column is
tested with a QC mix that includes both acidic and basic probes to
ensure inertness across multiple compound classes. Greater column
inertness improves peak shape and response, ensuring more accu-
rate quantitative results.
Try this top-performing, 1301-type column today and improve the
performance of existing methods for solvents, glycols, and other
polar compounds!
