Inert HPLC Columns

Both Restek and YMC have developed HPLC column lines featuring superior inertness, for use in challenging situations where column interactions can influence results.

Restek's columns are ideal for the analysis of metal-sensitive compounds, such as organophosphorus pesticides and mycotoxins.

Restek's inert LC column technology helps labs improve their analysis of metal-sensitive compounds. A premium inert coating applied to the stainless steel surface of these LC columns reduces the nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks.

This inert LC column technology is available on three column types:  Raptor Biphenyl, Raptor ARC-18, and Force Biphenyl. 
These new columns help bring the benefits of inert column technology to labs specializing in small molecule LC-MS/MS workflows.

YMC’s line is suitable for biomolecule and protein work.
Below is an article about optimizing the IP-RP analysis of protected and unprotected oligonucleotides.  You can also download a poster
on the influence of bioinert (u)HPLC hardware on biomolecular analyses.

Contact our Technical Team to discuss whether more inert HPLC columns could be beneficial to your lab.

FEATURED PRODUCTS

Force / Raptor HPLC Columns for PFAS Analyses
Restek has 2 brands of HPLC columns particularly well-suited for PFAS analyses; when combined with a delay column, the results are outstanding.

Force Performance LC Columns: Apply Force to Your LC Methods

• Long-lasting and reproducible – even with rapid cycling and elevated UHPLC pressures.
• Fully scalable between HPLC and UHPLC – easily transfer and optimize methods.
• Premium quality – backed by a 100% Pure Satisfaction Guarantee

Restek’s Force performance LC columns give you the power to maximize instrument uptime, increase productivity,
and transfer methods across your entire lab. The result of over twenty years of work.

Meet today’s workflow needs - and prepare for tomorrow’s - by applying Force LC columns in your lab.

Raptor LC Columns: Selectivity Accelerated

• Drastically faster analysis times.
• Better selectivity for improved resolution.
• Long-lasting ruggedness for dependable reproducibility.

The efficiency of superficially porous particles (commonly known as SPP or “core-shell” particles) provides fast separations
with low back pressures; speed up your analyses using existing HPLC instrumentation.

Eliminate the Impact of Instrument-Related PFAS Interferences by Using a Delay Column

Background PFAS contamination can interfere with low-level quantification requirements. Instrument-related background contamination can stem from LC components that contain fluoropolymers (e.g., PTFE), which can leach into mobile phase solutions. Switching to PEEK or stainless-steel tubing, containers and instrument components mitigates some of the risk of background contamination, the use of a delay column can significantly improve results even further.
