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
