"Waters HPLC are very good instrument with precision and accuracy. I like the Empower software very much among other available HPLC software. If handle properly by operator then observed less PM."

"The operation and maintenance of the instrument is user-friendly. The system offers a good advantage in developing and validating analytical methods with acceptable sensitivity and reproducible results across different Laboratories. The analytical throughput is excellent as users can fix and troubleshoot any instrument failures. The Alliance HPLC systems equipped with photodiode detectors (PDA) offer ultraviolet spectral contrast profiles which are very helpful in assessing the sameness and spectral purity of compound peaks. These profiles accelerate the understanding of the identification and characterization of new unspecified impurities and thus provide a way forward in the identification of new unspecified impurities. These instruments s also connected with universal detectors like refractive index (RI) detectors, conductivity detector, fluorescence detector, evaporation light scattering detector (ELSD) offer a very high advantage in developing methods for nonchromophoric molecules. A very precisely delivery pump with the option of supporting both isocratic and gradient mobile phase thus helping to develop shorter analytical methods to increase analytical deliverables and also to reduce the burden on the environment as the consumption of chemicals and solvents comes down drastically."

"As a pharmaceutical company, Waters Alliance's HPLC equipment are working almost non-stop. We have two comparable Alliance HPLCs, 9 years old and 3 years old that still on the same performance level. In terms of operating cost, Alliance HPLC is the number one as well. Modules do not require maintenance as long as the HPLCs are washed periodically with related solvents. Ready-to-use qualification tests on empower makes the qualification process easier. Even without service support, users can qualify the device with standard solutions and the column. When it comes to buying an HPLC, different offers can step forward. But with the Empower software, Alliance HPLC is not comparable with others."

"Easy to use machine and columns. Impressive technical support."

"Tech service is very good and supportive."

"Great and innovative equipment, excellent reproducibility. Good for assay, impurities, cleaning residues, identification test, etc. Provides reliable results.

"This HPLC from Waters is a very stable instrument, good for analyzing APIs in drug formulations. I use this instrument for routine analysis in quality control, method validations, and method development. The fact that you can prep the whole system without it being actually connected to the software is very beneficial and speeds up the overall analysis process. The max pressure this system can handle is 5000 psi which is pretty decent for most HPLC analysis. It is a very sturdy and robust instrument and gives good reproducibility, precision and accuracy."

"Waters' Alliance is the best high pressure chromatograph on the market. I have been using its older and newer versions for almost 20 years. Smart looking, ergonomic and intuitive handling makes it user-friendly. The daily routine work is very convenient - chanching of usable accessories (filters, columns, tips, lines etc.) is very easy. The Waters' second face is Empower. This is my top of the top - the best chromatographic program I have ever seen. Hundreds of options, variety of usable calculation tools makes it calculates everything for you. Creating your own "custom fields" is very unique - it can 100% personalize your needs in performing, processing and reporting your data. The third strong advantage is a service support. Service-men are fully professional staff that fully guide you with the troubles that you could have with your device and software. Alliance is not cheap but it is really worth the price."

"This system is reliable and fairly easy to use, but it is hard to maintain the tubing; it tends to clog up very often. If you are dealing with complicated matrices it tends to carry over for matrix as well as analyte. It is a useful tool for certifying std by UV for purity as at high flows and high concentrations it performs a lot better. I recommend for Protein Analysis and for certifications of std with a PDA detector."

"I have had a long research history with Water's HPLC (amino acids, catecholamines, caffeine) and this is the equipment I would want for my lab."

"It’s a good system, easily automated and compatible with other LC systems. "

"Lasted a long time but starting to break now. I would recommend it to someone, however it would be good if it came with a list of compatible consumables e.g. vials, lids."

"Very easy to use. I would recommend it to other scientists because I had great results using this equipment."

"High quality, easy to use, good to connect to. A good value mass spectrometer."
