5cm x 100um C18 UHPLC trap column with 2 x nanoZero® fittings compatible with nanoViper™ 3 Pack
Chromatographic trap columns are essential in proteomic UHPLC–MS workflows, improving analyte focusing and enabling rapid sample loading with in-line sample clean-up to protect analytical columns from blockages and contamination while reducing ion suppression. These benefits extend column lifetime and reduce maintenance, supporting robust, high-throughput, and reproducible proteomic analyses. Despite these advantages, trap columns traditionally sacrifice peptide and protein identifications compared to direct injection. The NanoShield™ C18 5 cm × 100 μm trap column eliminates this trade-off – delivering direct injection-level performance; providing superior peptide identifications, peak quality, and hydrophilic peptide coverage compared to other traps.
Next to no peptide ID loss
Extends column life, reduces maintenance costs
Improved reproducibility across thousands of injections
Enables hundreds of samples per day

Aurora Gen 3 columns have been discontinued from the manufacturer, but we still have a selection of the most popular sizes and configurations, get them while they last! Great value on them, as prices have increased on the newest Gen 4 columns.
If the form does not work for your selected column, it is out of stock. Please refer to the newest list of Gen 4 column on the other page.
IonOpticks’ new generation of UHPLC columns reimagines what proteomics separation technology can achieve.
Find here the full list of the latest Gen 4 Aurora columns from Ion Opticks. We strive to keep these very popular items in stock, but importing is a tricky business lately, so plan in advance important purchases with us to ensure availability.
We are located just north of Boston, trying to keep the single cell proteomics community supplied with columns and other hardware.
Use the ALS to See the Spray in Thermo Scientific nanospray sources. These unique 3D-printed devices position a high intensity LED below and to the side of the camera path, illuminating the nanospray plume, which will allow you to:
Confirm spray voltage
Confirm LC flow
Optimize applied spray voltage
Optimize tip position
Confirm spray integrity during analysis
Auxiliary Light Source types 1 and 2 for Flex Ion Source (ES072 and ES071 respectively) and types 3 and 4 Easy Spray Source. (ES081 and ES082).

The ColuMate™ System is an easy-to-use capillary column heating solution for nano-LC/HPLC system. It enables simultaneous but independent control of two heating channels, with both manual and remote control for maximum convenience. Each channel provides 30–60 °C of consistent column heating (±0.5 °C) from inlet to outlet. The reusable heating chamber features a simple clamshell design for easy installation and exchange of ColuMate-Ready columns. Our cartridge-based approach is suitable for most column sizes and can be adapted to many third-party columns.
The μPAC Neo Plus column line offers higher resolution than the previous generation of μPAC columns, ensuring that you can extract the maximum amount of information from highly complex samples using low-flow chromatography. Column installation is simple and reliable with Thermo Scientific™ nanoViper™ Fingertight Fittings.
The μPAC Neo Plus column range is the ideal choice for a variety of proteomics experiments, including fast label-free quantitation, comprehensive identification, and single cell analysis.
Performance and Robustness
- μPAC Neo Plus columns operate at moderate pressures, allowing for longer flow paths that increase separation performance and sensitivity. Operating at lower back pressures also extends column lifetime.
Column-to-Column Reproducibility
- The unique micromachining manufacturing of our μPAC Neo Plus column line produces columns that are virtually identical. This results in increased injection-to-injection and column-to-column reproducibility, providing you with greater confidence in your results throughout the duration of a research study.
Perfect Flow Path Order
- μPAC Neo Plus columns are designed with a perfect flow path order, eliminating heterogeneous flow paths. The ordered flow path of the columns minimizes dispersion to the overall separation, resulting in sharper and more intense chromatographic peaks.
Dr. Maisch offers a complete portfolio of nano flow solutions, covering classic packed fused-silica columns as well as integrated-emitter technologies. All of these columns are available with your choices of Dr. Maisch media in a format that fits your current workflow.
Our product families – MyMap, MySep, NanoFusion, NanoFusion Sword, and NanoFusion CSX– represent high-performance alternative hardware solutions to established platforms like PepMap™, PepSep™, Odyssey™ and Aurora™. Built with high-performance C18 materials and strict QC, they provide robust lifetimes, excellent batch-to-batch reproducibility, and flexible configurations for every workflow.
These columns are available in all popular sizes with any Dr. Maisch brand media. Discounts for 4 and 10 packs available.

Nanospray emitters by MicrOmics are a unique and highly valued product, as they have tip angles less than 4 degrees in both a Constant ID Etched Tip (CET) in 10um ID or 20um ID (previously called Stinger Tips), or in a Pulled Etched Tip (PET) that has a reduced tip orifice of ~8um for improved spray stability at low flow rates. Various lengths and IDs can be ordered as well, please contact us directly for details.
All tips come 5pc/pk in a convenient storage box, common sizes carried in-stock at ESI Source Solutions.
These columns are fritted glass capillaries with several options for inlet and outlet fittings to match your system exactly for ease of installation and continuity across platforms. All of these require some type of nanospray tip connection, made easy with the male 1/16” outlet fitting to many tip adaptors and reducing union fittings.
