ide-bore and narrow-bore Picotips™
can be nested to create versatile,
ultra-low volume ESI emitters. Here, a

30 µm tip fabricated from 360 µm OD tubing has
been inserted into a 15 µm tip made from 450 µm
ID (670 OD) fused silica tubing.

Patented Multi-layer Conductive Coatings

New Objective uses a patented (U.S. Patent 5,788,166), multi-layer coating process. Our pure gold layer is overcoated with an inert, electrochemical-

ly stable dieletric layer, locking the gold into place. The resulting coating has excellent resistance to ESI solvent exposure and exceptional electrochemical
stability. To try and improve coating performance, other manufacturers increase the mechanical durability of the gold layer by introducing alloy or inter-layer
metals. During handling the coating may appear to be more durable, but it may not yield improved ESI performance. These alloy and inter-layer metals can
actually reduce the coating’s electrochemical stability resulting in coating degradation at the tip.

Stability With Stop/Start Performance

The figure on the left shows the stability of signal at three time scales. The mod-

ulation in current is due to turning the spray voltage on and off. Note how the ion
current returns to its former level. This tip was sprayed without failure for over 3
hours and was “retired” still functional. The total ion current is (through 3 RF-only
quadrupoles) from a 360, 50 (ID/OD) needle with a 5 µm ID tip, operating at 60
nL/min spraying 20 µM Ubiquitin in 2% HoAC.

Select the right tip for your mass spectrometer

For optimal results - and without the need of additional equipment - some mass spectrometers require a specific size emitter. The most

common systems and their respective emitters are:

Covers SIS products, services, promotions, news, and other mass spectrometer related information.

28 Aug 2013: Nanoliter Dispensing Devices can be used to place media on the MALDI plates for MALDI/TOF instruments, but the most exciting ability of this device is to collimate droplets directly into the ion source like electrospray (ESI), the unique concept being that nearly 100% of the droplets go directly into the source versus <1% from ESI, giving a huge increase in sensitivity. We believe this could be the next big advance in LC/MS sources. [NEW]
