User-friendly, good for Mw - less accurate for Mn.
Application Area:Size exclusion chromatography
"The OmniSEC system is great for running all types of samples for absolute MW.The support from the Malvern team is also great as we run into issues like temperature control problems, method development challenges, and issues in chromatography. "
Manufacturer's ResponseThanks for the feedback on the system and the Malvern support.

One of the best GPC/SEC instrument/software packages currently available.
Application Area:Polymer GPC
"Very nice integrated GPC package. Pump system isn't the absolute most stable on the market, but is much better than previous generations. Unless you want to piece together your instrument yourself from multiple manufacturers this is quite good. Detection array is likely one of or the best for GPC currently on the market. The software is very user friendly and hides much of the rigorous calculations behind the scenes (for better or worse). It's great for routine GPC/SEC characterization (99% of what everyone does). The software still has some room to grow in enabling advanced operation/control to do custom runs/calculations. Overall it is a great package. Malvern also backs it up with great customer service and access to world experts in GPC/SEC if you need it."
Manufacturer's ResponseThanks you for your review, we are glad to see that this product is filling your needs, else don’t hesitate to contact us.

Satisfied OMNISEC user
Application Area:Surfactants and Polymers
"I absolutely love the new OMNISEC system. As a user of the older GPC MAX and TDA 305 Sseries, I am very impressed by all the upgrades incorporated into this new system. Primarily, I am happy with the new user friendly software, sensitivity and external column manager ( quicker column changes). Since we purchased OMNISEC, we’re able to deliver more sensitive data, so our ability to support decisions has been directly enhanced. In an analytical lab like ours that operates so many techniques with relatively few people, improving productivity is a major gain."
Manufacturer's ResponseThanks for the positive feedback. It is great that you are finding the software user friendly and that the enhanced sensitivity is offering you real value.

Great results, great instrument, software could use a little improvement.
Application Area:Analyze polymer molecular weight and composition
"The triple detection GPC system we have in our lab is very easy to use. I love the autosampler and the automation associated with purging and switching things out. However, the software has some room for improvement. It would be nice if data files and/or method files could be deleted. I have found multiple times I created an incorrect method file or have data files I don't want remaining on someone else's computer and I cannot delete them. That is really my only concern with the equipment. Aside from that, the GPC itself runs beautifully, the software is very easy to use, and the customer service is wonderful!"
Manufacturer's ResponseGlad that you love the autosampler and the automation system and that our customer support is so helpful. Our development team will take your review into account for future improvement of the software

Good insturment, software has some issues, customer service is great
Application Area:Novel polymer characterization
"The instrument itself is easy to upkeep. However, the software especially the sample queue is buggy. The customer service is great with the company however and they are always ready to help."
Manufacturer's ResponseThanks for the feedback. Apologies for the software issues, but please feel free to let us know any problems you have and we can make sure they are fixed in future releases. And as ever, don’t hesitate to reach out if you have any questions or need any support.
