Optimal Online Analysis

Fused-silica PicoTip^® emitters for online electrospray are available in the SilicaTip™ and the TaperTip™, which differ in size and operational flow rates. TaperTips are very robust emitters used in microspray applications. Your emitter-mounting hardware must accommodate 150 or 360 µm outside diameter (OD) fused-silica tubing.

SilicaTips™

Fused-silica emitters engineered for continuous-flow nanospray and LC-MS within a flow rate of 20-1,000 nL/min. Each tip is video inspected to ensure that tip shape and taper conform to designed specifications and have a clear path. SilicaTips™ are able to perform electrospray for hundreds of hours of continuous operation (more than 800 hours with an MeOH/Water/Acetic Acid mobile phase) without a loss of coating. Benefits Durable and rugged Consistent, sustainable spray Wide selection of ID and tip sizes for different applications and flow rates Available in range of lengths to fit a variety of mass spectrometer systems Multiple coating options to fit a variety of contact techniques Custom sizes available Contact New Objective to find out more SilicaTip Pricing

TaperTips™

Designed for microspray flow rates (0.2 to 3.0 µL/min.), fused-silica TaperTip™ emitters are specifically tailored to meet the rigorous demands of continuous-flow microspray and LC-MS. Each tip is video inspected to ensure that tip shape and taper conform to designed specifications. Benefits Proven for flow rates of 0.2 to 3.0 µL/min* Reduced particle clogging External taper only Extremely rugged and long-lasting Wide selection of tip IDs to meet specific applications Multiple coating options for a variety of contact styles TaperTip Pricing

Metal TaperTips™

Precision trimmed and polished, stainless steel TaperTip™ emitters are micro-spray workhorses. Extremely durable, each tip can last through months of delivery time. Emitters are easily inserted into a microsleeve to enable use with systems requiring 360 µm OD tip sizes. Benefits Outstanding durability, reliable performance > 1,000 hours Accomodates a wide flow range: 0.2 - 1.5 µL/min Provides a stable, reliable spray No internal taper means less clogging Reusable Metal TaperTip Pricing
