An essential part of my routine activities! Fabulous!
Rating: 4.7

  • Application Area:Analysis of different carboxy methyl cellulose and maltose samples

"The MALS detector is one of the champions in determining MW of large molecules, what’s fascinating about it is the fact that it could easily differentiate between 10kDa, 25 kDa, 49 kDa, 90.5 kDa with ease with extremely narrow margin of error. The product was delivered to us seem less was with true professionals, the next day the engineer drop by in our lab and installation was done in a flash. Whenever we encountered slight problems, they would always hear us patiently and delivered solutions over telephone, if not done then they would personally visit and rectify. I would highly recommend this detector."

A much added benefit to typical SEC.
Rating: 5.0

  • Application Area:Analysis of biologic drug candidates.

"The instrument is a must have for analysis of protein therapeutics. It gives a huge advantage to typical analytical SEC when used as SEC-MALS mode because it gives you the absolute molecular weight rather than comparing peaks to a standard. This can help avoid misinterpretation of column interactions as aggregation as well as other common mistakes."

Rating: 5.0

  • Application Area:Analytical chromatography & Protein Purification

"Easy to use software especially if you attend their training classes at Light Scatter University. By far the most superior application to determine molecular weight & oligomeric state of a protein or protein complexes. Customer service respond to your request in a very timely fashion and their excellent professionalism and expertise will be able solve any technical inquires you have."

Rating: 3.0

"Instrument used to determine the masses and rg of polymers (polyamide-imide) Easy to use instrument and software but difficulty to exploit the data (method of integration, drift baseline ...) and especially hard to understand the conformation plot, for example"

A must have item in polymer analysis!
Rating: 5.0

  • Application Area:Polymer characterization

"Our biopolymer laboratory has been using Wyatt instruments, including the miniDawn Treos, for many years. This instrument is configured with FPLC/HPLC third party equipment for SEC analysis. The setup of the instrument is straightforward. I consider the miniDawn Treos a great investment as our Wyatt instruments are running almost every day with reproducible results and absolutely no problems. The Wyatt company always offers excellent customer service and technical support which is a must have item in polymer analysis."

Rating: 5.0

  • Application Area:Protein Mw determination

"Our lab uses the Wyatt instruments (TREOS, QELS and rEX) for molecular weight and Rh measurements with our SEC methods. Training included with the instruments is thorough, and the instruments are easy-to-use after LSU. SEC-MALS is an easy way to determine the online Mw/Rh without adding further methods. Wyatt support reps are quick to reply, and thorough with answers. Would definitely recommend."

Rating: 4.7

  • Application Area:Protein science and structural biology.

"My lab has been using this equipment for the past three years. It is so reliable and easy to use that it is used by all the students. We use it to determine the oligomeric states of our proteins and complexes and have obtained spectacular results with it. It has also completely changed our way of looking at size exclusion chromatography. We use for every single project now. Our best purchase."

Very good instrument for the absolute determination of molecular weight in carbohydrate samples
Rating: 4.7

  • Application Area:Analyze carbohydrate samples for average molar mass and mass distribution

"The instrument works very well for the absolute determination of molecular weight of the carbohydrates that we are analyzing, except for the very highest molecular weight fraction (above 10000 kDa). We have some small problems with increasing noise levels over time, which means that the cell needs to be cleaned from time to time, but else that that the setup is working very well. The use of the instrument requires a bit of skill and understanding, but Wyatt's training program does an excellent job in educating the users in this regard. The investment in the miniDAWN TREOS has certainly been a good one for our company."

Perfect detector combination for our analytical needs, can't stay in business without them
Rating: 5.0

  • Application Area:Analysis of monomer solutions for the presence or absence of polymer units

"Due to the nature of our materials, no chromophore and not RI sensitive enough, we have employed the miniDawn MALS detector in our process. The development of methods was straight forward, validatable, and reproducible. We have now employed this technique in all of our in-process/finished product testing and in our equipment cleaning procedures. We are so impressed with the instruments and the after sales support of our systems we have just completed the purchase and installation of a second set of instruments, the miniDawn and T-rEX."

The Wyatt treos is great when used in combination with SEC, but not worth the money for batch applications.
Rating: 3.3

  • Application Area:protein stability

"Primary application is to verify molecular weights of proteins and aggregates when coupled to SEC. I think the software is very versatile and easy to use. I found using the instrument in batch mode to be extremely tedious and not very informative. I was disappointed since this application did not measure up to my expectations. I found the instrument easy to use and to calibrate and required little maintenance. Probably the most useful was customer support. The reps I spoke to have always been highly knowledgeable and eager to help. "

Rating: 4.7

  • Application Area:Analyze of protein-conjugate

Review date: 19 Apr 2009 | miniDAWN®

The miniDAWN® multi-angle light scattering (MALS) detector connects to most HPLC, GPC, FPLC or FFF separation systems to determine absolute molecular weight, size, and conformation of peptides, proteins, small polymers and nanoparticles, in solution, without reference to calibration standards. 

Eliminate column calibration and idealized assumptions, gain certainty with first-principles MALS analysis. The miniDAWN provides high sensitivity, a wide range of measurement, productivity and versatility second only to that of the DAWN® MALS detector.

Features: 

  • Sensitivity in SEC-MALS mode: 25 ng of 100 kDa polystyrene in THF, or 500 ng of BSA in PBS, using 7.8 x 300 mm SEC columns 
  • Range of molar mass: 200 Da to 10 MDa (may vary with molecular composition or solvent) 
  • Range of rms radius Rg : 10 nm to 50 nm 
  • Integrated ultrasonic cell cleaning module
  • DLS: optional WyattQELS™ embedded dynamic light scattering detector for particle sizes from 0.3 nm to 50 nm (Rh
  • Touch-panel display for immediate access to data, diagnostics and settings
  • Serviceability: fully field-serviceable with extended self-diagnosis of field-replaceable flow cell and hardware modules
  • Software: ASTRA® chromatography software provides comprehensive analyses and user-friendly features including HPLC control, “One-click MW” and user-designed reports. Optional 21CFR11 support for GMP.

Applications:

  • Proteins: absolute molar mass, size and stoichiometry of monomers, oligomers, complexes, aggregates and fragments.
  • Glycoproteins, detergent-solubilized membrane proteins, PEGylated proteins, protein-polysaccharide and protein-DNA complexes; heme-containing proteins that absorb laser light
  • Protein-protein and protein-nucleic acid interactions
  • Polymers: absolute molar mass and size (distributions and moments), conformation, branching and second virial coefficient
  • Linear or branched polymers, co-polymers
  • Nanoparticles: size distributions, structure, encapsulation and concentration of vesicles, dendrimers, small viruses, VLPs, and more
  • Most aqueous and organic solvents
