The PST-mTips and PST-mgTips are patent-pending, ground-breaking metallic spray emitters for extremely robust both nanospray and microspray of a large range of buffer compositions and both positive and negative ion sprays. They are direct replacements for the laser-pulled 360 um o.d. fused silica tips. These emitters can also be “regenerated” after prolonged use and loss of spray, making them very long-lasting.
PST-mTip : Superb spray performance for both +/- ion spray at low spray voltages (1.8-2.4 KV). Durable for negative ion spray but may require regeneration after 2-3 days of continuous spray.
PST-mgTip: Excellent for positive ion spray and durable. Requires a higher spray voltage ~ 3.2-3.5 KV.
PST-mTip-25, PST-mgTip-25: The 25 um i.d. mTips are suitable for flowrates from nanospray up to 2 uL/min
PST-mTip-50 ,PST-mgTip-50: The 50 um i.d. mTips are capable of very robust nanospray up to microspray of 10’s of uL/min. Due to the potential of causing more dead volume than the PST-mTip-25, the PST-mTip-50 is used when the flow rates are above 2 uL/min.
For the performance of the PST-mTips in actual analyses, please view the results in an ASMS poster, and also results of the separations of fatty acids, lipids, and phosphorylated compounds provided by our user H-K Lim, PhD, of Janssen Research Labs.
The PST-patented plastic nozzles are especially good for samples in complex matrices. They are completely non-clogging. Each nozzle emitter comes with a 6 cm long, 20 um i.d. fused-silica capillary support with a tapered end that eliminates essentially all the dead-volume into the nozzle. The nozzle may also be purchased by itself and be placed on the user-supplied fused silica 360 um o.d. capillary column with a tapered but flat-ended cut.
