<strong>Column</strong>s for Special ApplicationsZORBAX PrepHT• Easy scale-up from analytical to preparative scale with ZORBAX phases• Fast preparative separations, up to 2000 mg• 5 to 7 µm particles for high efficiency and high yield• Easy to install finger tight connections seal up to 5000 psi/350 barHigh purity, high recovery and high throughput can be easily achieved with <strong>Agilent</strong>ZORBAX PrepHT columns. These are available in a variety of bonded phases – Eclipse XDB,StableBond, Bonus-RP, and Extend-C18 – for optimized resolution and loadability underany conditions.ZORBAX PrepHT columns are packed with 5 and 7 µm particle sizes for very high resolution.The high resolution allows high loadability, high yield, and high purity of compounds. Thelarger diameter columns and mechanically stronger ZORBAX particles allow for flow rates upto 100 ml/min, thus increasing throughput.ZORBAX PrepHT columns are designed for rapid scale-up from analytical to preparative scalewithout losing resolution. For complex separations on larger columns (21.2 mm ID, 150 mmlength and longer), <strong>Agilent</strong> has carefully chosen the 7 µm particle size to achieve a balancebetween high efficiency and high loadability.94 Order online at www.agilent.com/chem/store
