Agilent Technologies J&W PLOT Columns
PLOT columns are ideal for separating compounds that are gases at room temperatures. Agilent Technologies offers a comprehensive line of PLOT columns for analysis of fixed gases, low molecular weight hydrocarbon isomers, volatile polar compounds and reactive analytes such as sulfur gases, amines and hydrides. Our PLOT phases are offered in dimensions from 0.25 to 0.53 mm ID, allowing for easy column selection for various detector and system requirements. For GC/MS systems, we offer several small diameter columns with truly bonded and immobilized stationary phases, eliminating potential detector fouling due to particle generation
Agilent Technologies J&W PLOT Columns
 
Column  Stationary Phase Typical Applications
     
GS-OxyPLOT High selectivity adsorbent
High retention for oxygenated hydrocarbons (Methanol retention index +1400). Useful for alcohols, ketones, and ethers in gasoline, diesel,  and C1 to C4 hydrocarbon streams.  
HP-PLOT Al203 KCl Aluminum oxide deactivated with KCl
Least "polar" Alumina phase. Lowest retention of olefins relative to comparable paraffin. C1 to C8 hydrocarbon isomers. Column of choice for accurate quantitation of dienes, especially propadiene and butadiene from ethylene and propylene streams.  
GS-Alumina  KCl Aluminum oxide deactivated with KCl   
Least"polar" of the Alumina columns. Light Carbon analysis
HP-PLOT Al203 S Aluminum oxide deactivated with
sodium sulfate  
Excellent general use Alumina column for light hydrocarbons: C1 to C8 isomers. Best for resolving acetylene from butane and propylene from isobutane.  
GS-Alumina   Aluminum oxide with proprietary deactivation
Most "polar" of the Alumina columns. Highest retention of olefins relative to comparable paraffin. Excellent general use Alumina column for light hydrocarbons: C1 to C8 isomers. Best for resolving cyclopropane from propylene. Good stability and recovery from water saturation.  
HP-PLOT Al203 M Aluminum oxide with proprietary deactivation
Most "polar" of the Alumina columns. Highest retention of olefins relative to comparable paraffin. Excellent general use Alumina column for light hydrocarbons: C1 to C8 isomers.
GS-GasPro Proprietary, bonded
silica-based
C1 to C12 hydrocarbons, CO2, trace-level sulfurs, hydride gases, inorganic gases, halocarbons, SF6, oxygen/nitrogen separation at -80°C.  
GS-CarbonPLOT   Bonded, monolithic carbon layer  
C1 to C5 hydrocarbons, CO2, air/CO, trace acetylene in ethylene, methane.  
HP-PLOT Molesieve 5Å molecular sieve zeolite  
Permanent and noble gases. Thick and thin films available. Thick film column will resolve argon and oxygen at 35°C.  
HP-PLOT Q   Polystyrene-divinylbenzene  
C1 to C3 isomers, alkanes to C12, CO2, methane, air/CO, water, oxygenated compounds, sulfur compounds, solvents.  
GS-Q Porous divinylbenzene homopolymer
Polarity between Porapak-Q and Porapak-N
HP-PLOT U   Divinylbenzene/ethylene  
More polar than HP-PLOT Q and GS-Q. C1 to C7 hydrocarbons, CO2, methane, air/CO, water, glycol dimethacrylate oxygenates, amines, solvents, alcohols, ketones, aldehydes.
