EcoSEC GPC/SEC Systems by Tosoh Bioscience

"We as a team value Tosoh GPC because of its all-in-one approach. In addition, the easy online/offline monitoring of instrument conditions, high reproducibility, repeatability and accuracy, make the instrument user friendly. Furthermore, online after-sales services are perfect. I will recommend other users of GPC to buy this instrument from Tosoh."

"The the company has a huge knowledge and experience in the field of GPC (SEC). The product is very reliable and easy to use. The software supports the work significantly."

"Compact and easy to use. We chose this system because we want to have something we could use later as an example GPC/SEC system during student training. The price value is really great. Tosoh support in Germany also really good."

"Problem: High amount of waste of eluents: It would be great if the software could control the "waste" lines of for eluents, and provide the possibility of feeding back the clean eluent (recyling). For example: purge with eluent after the test for ab. 10min into the waste, then switch to recycling mode - do not have to do it maually (change the waste line position). Software problem: Not able to set up special access, for example: Not allowed to modify EQ set-up (method), but allowed to prepare measuring/calibration curve. I have to give all the access to be able to creat calibration curve."

"Easy to use robust equipment. I really love Tosoh columns."

"In my practice, I used some different GPC instruments: Waters GPCV 2000, Waters HPLC Breeze, Malvern Viscotek HT GPC 350. 2 years ago my company bought a Tosoh EcoSEC HLC8320. The best was the Tosoh because: 1. Good price 2. Online/offline monitoring of instrument conditions 3. Online column check 4. usability - in 2 years I had no problems 5. High reproducibility, repeatability and accuracy 6. perfect applications. My favourite is peak separation, it is very good with copolymers presentation. I have a little experience of working on Shimadzu UHPLC instruments - in my opinion, the software organization not very good 7. The most important is after sales service. If compared with Waters and Malvern - the best one is Tosoh. In terms of disadvantages, if you use RI+UV other detectors (e.g. MALS, Visco) there will be some external blocks. It will need additional software and adjustment. This is the best way for the user (not for service engineers), because it will be inconvenient for maintenance and repair, but it is solvable - all additional detectors and GPC in one block. "

"GPC from Tosoh Bioscience is an easy to use instrument. Online after-sales services are perfect. I have used this instrument since April 2019 and am very satisfied with the reproducibility of results. I will recommend other users of GPC to buy this instrument from Tosoh."

"The EcoSEC fits in our existing equipment. The all-in-one approach is appealing. Service during installation was helpful and rapid in response."

"Our application is synthetic rubber analyzing. Very high reproducibility even with samples prepared in different labs. Very good separation and fast results with semi-micro columns. Most valuable is not needing maintenance for a long time, just good solvents is enough for proper working. It was a good surprise to get results not affected by temperature and draught in the lab. The old competitor's instruments are more temperature vulnerable. Pre-sale sample testing was a great opportunity to check the instrument's strengths and get confidence in the best choice. After sale service; prompt reaction to every question about instrument and tech support by the service team which is always on top and proving superb quality."
