I will recommend Waters to my colleagues
Development laboratory analysis in pharma
I have worked with the Waters since 2004 and the equipment is very good and gives good results and sensitivity. Post sales service is very good too.

Good and reproducible results achieved.
Drug discovery
Very easy to use. The column gave us a very nice peak, good resolution, and nice separation of small amount impurities.

Easy to use, wouldn't use column without these guard columns.
Steroid analysis
These are very easy to use, just screw onto the head of the column and reinstall connections, and then you can be assured that your LC column is protected from particulates and other substances that can interfere with your chromatography. We replace these about monthly, which extends the lifetime of our actual column. Provides reproducible chromatography, no significant shifts in retention times, and excellent peak shape.

Easy to use and consistent product.
Analyze small molecules in a variety of sample matricies
The guard column is easy to use and the quality of the product is consistent. The lifetime of the product is reasonable.

If not installed correctly they leak, then you've wasted several hundred dollars.
Measuring anticancer drug (and metabolites if necessary) in clinical samples of multiple biospecimen
When installed correctly, the VanGuard guard columns work great. However, if not installed correctly, as it can be difficult to set the ferrule when there's loose, tiny parts that need arranged, then the column is useless and you've wasted money. training new employees is difficult because you're sometimes wasting thousands of dollars of 4-5 guard columns until they learn to do it correctly every time.

An easy to use product that provides maximum column protection.
LCMS urinalysis of Drugs of Abuse
I use these columns on our Waters Aquity HPLC instruments and they are fantastic! They are easy to use and easy to install. There are even YouTube videos to help you out, with instructions on how to install the guard columns properly. They protect our columns for hundreds of injections and we do very little to clean up our urine samples. I highly recommend this product.

This product has prolonged column life saving time and money in the lab.
Analyze composition of raw and in-house materials produced.
This product is effective in helping to prolong column life. It has been very useful especially for large molecule column build up and raw material contamination. The value for the money is in the fact that this product can prevent having to change the column as it acts somewhat like pre-column filter and costs less than the column. Once installed it is very easy to use but the installation can be a bit difficult to set the ferrule and not bend the rod inside. This can lead to leaking or having to use a new VanGuard. There is not much to after sales care for this product is a consumable.

Good results, quality product
Pharmaceutical impurity test
The column guard effectively protect our column and conform with USP specification in terms of size of guard column.

High benefit-cost ratio & reproducibility make Vanguard columns a good investment.
Analyze small molecules in human biological matrices.
Vanguard guard columns are effective in protecting analytical columns for most bioanalytical applications, but are most effective and reliable when combined with an efficient and robust sample extraction method. This is most important when working with biological matrices. When followed by a robust sample extraction method, the Vanguard columns provide high quality results and reliable reproducibility. Vanguard pre-columns are easy to use, and can provide a high benefit-cost ratio to the laboratory when samples are processed efficiently.
