Feature/Benefits

Analytical TLC

HLO

Hard-Layer: Organic Binder HLO the most abrasion resistant high resolution TLC product available in our program. Write directly on the plate. Outstanding detectability, sensitivity; Minimal breakage.

· High Resolution
· Standard of the Industry
· Durable Reflective Surface

Alumina A, B, N

Select the pH most appropriate to your separation,
A=Acid, B=Basic, N =Neutral. Alumina is stable a pH 4 -
14 and can be used to separate most compounds,
especially basic.

· Ideal for the Separation of Basic
Compounds
· Standardized Particle for TLC, Prep TLC
· Stable Reproducible Layer

PEI - Cellulose

Ideal Anion ion-exchanger for many life science
applications e.g. nucleic acid compositions. Keep
refrigerated at 4ºCelcius to avoid discolorization.

· Long Chain Anion Exchanger
· Bio-Life Science Applicaitons
· Stable Reproducible Layer

Cellulose

Available as microcrystalline, Avicel, and Native (MN
layers for the separation of polar compounds via liquid -
liquid partition chromatography.

· Liquid-Liquid Partition Separation
Mechanism
· Ideal for Polar Analytes
· Available as Crystalline or Native Fibers

HPTLC and "S" - HPTLC Advanced Layers

HPTLC

A 5 micron particle, 200 micron thick layer, suitable for
very difficult separations. Spots of 1-2 mm will optimize
separations. Three to five times the resolving power of
TLC. Fast development time.

· Obtain 3-5,000 Theoretical Plates /5 cm
· Ideal for the Most Difficult Separations
· Resolution similar to HPTLC

"S" HPTLC

The ultimate in separating power; 3-10 times the
resolving power of TLC. Technology and separation
dependant on a 3 micron particle; 100 micron layer.
Separate nanogram - picogram quantities. Spots of 1-2
mm will optimize separations.

· Smallest TLC Particle (micron), Highest
Resolution
· Fast Analyses
· Thin, Highly Reflective Surface

Prep TLC

Prep TLC

Select 100, 200, 250, 500, 1,000, and 2000 micron layers
according to the amount of material to be separated.

· Readily Isolate mgm - gms
· Standardized Particle for Prep TLC, Prep LC
· Wide Variety of Prep TLC Layers

"S" HPTLC

The ultimate in separating power; 3-10 times the resolving
power of TLC. Technology and separation dependant on
a 3 micron particle; 100 micron layer. Separate nanogram
- picogram quantities. Spots of 1-2 mm will optimize
separations.

· Smallest TLC Particle (micron), Highest
Resolution
· Fast Analyses
· Thin, Highly Reflective Surface

Selected Backings

Glass Backing

Use glass for optimum separation and with aggressive
mobile phases. Inert backing will not react with selected
detection sprays. Easy to handle. Best resolution.

· Resistant to Virtually all Sprays, Eluants
· Rigid Support for Optimum Resolution
· Available in Micro-Macro Sizes

Plastic
and
Aluminum Backing

Unbreakable and easy to handle. Cut into any size. Easy
to isolate one spot for subsequent elution/detection. Can
be easily included (attached) to lab reports.

· Cut into Virtually any Size
· Readily Isolate any Spot for Subsequent
Detection
· Ideal for Documentation
