VanGuard™ Pre-Columns for UPLC Separations
VanGuard Pre-Columns for UPLC® separations are guard columns that are designed for use with the ACQUITY UPLC® system. These guard columns use an ultra-low volume design (patent pending) that efficiently protects UPLC column performance. This ultra-low volume design does not compromise the UPLC holistic design approach to higher efficiency, greater resolution and increased throughput. Guard columns are typically used in appli…

Great column
We use it for analitical detection of drugs in human plasma samples using UPLC system to perform PK/
We always achieve high quality and reproducible results.

Product as described.
protect Column from particulates entering from contaminated samples
I purchased this column protector for an R& D purpose. This column has done what it was intended to do.

Works with appropriate column very well.
Drug Product Analysis
Used for drug product research. Is suitable for research in our applications as we have ordered vanguard columns in the past as well.

We are happy with results and faster analysis times!
Analyze caffeine in beverages
We recently switched our current method over from HPLC to UPLC. We are happy with our results and faster run times. Our run times were 8 -10 minutes and now we see results in 4-5 minutes.

Fantastic when it works, not so hot for on-site care needs.
Small molecule separations, high throughput sample analysis
Waters pre-columns work well at extending the life of the main column on our system. They're easy to use and change out when necessary. The UPLC system is a rock star when it works which is a majority of the time. Waters after market support is great for pre-arranged maintenance, like a PM visit. 3-stars for after sales care as getting a technician on-site for unexpected maintenance needs can take days and we're only a couple hours away from their San Francisco bay area offices.

These little guys are great!
Analyze organic micropollutants in environmental matrices
These columns are great and have a very long lifetime when properly cared for. They are perfect for protecting our separation columns.

Great Product and easy to use.
Industrial Polymers, additives, catalysis & dyes
Very easy to install. Extends the column life a lot. We routinely using these guard columns and happy with the product.

Extends column lifetime
Analysis of drug product and metabolites in biological matrices. also used in peptide/protein analys
Easy to install, extends column lifetime by catching the crud. Definitely cheaper to replace than a column when clogged. No noticeable change in chromatography

Excellent design and performance.
Pharmaceuticals
No loss of peak performance as compared to no precolumn use. Easy to configure to columns.

VanGuard Pre-Columns for UPLC® separations are guard columns that are designed for use with the ACQUITY UPLC® system.
These guard columns use an ultra-low volume design (patent pending) that efficiently protects UPLC column performance. This ultra-low volume design does not compromise the UPLC holistic design approach to higher efficiency, greater resolution and increased throughput.
Guard columns are typically used in applications where complex, unpredictable and demanding samples are analyzed. VanGuard Pre-Columns are the first guard columns specifically designed for routine use at pressures up to 15,000 psi (1,000 bar). The first VanGuard Pre-Columns for UPLC separations will be available with 1.7 µm ACQUITY UPLC BEH C18 chemistry. Additional VanGuard Pre-Columns will be released as they become available.
