Combustion Ion Chromatography – automated determination of halogens and sulfur in solid and liquid samples by Metrohm AG

"Our unit formed a relationship with Metrohm Instruments as early as 2003. We first used the 785 potentiometric titrator, and then I purchased the 888DMP full-automatic potentiometric titrator in 2014. It has been with me for 8 years now. Fight with me on the front line of quality and safety control of breeding inputs. Even if the operation is overloaded, the data can always be produced stably, with excellent reproducibility. Occasionally, when encountering some problems, your engineers can always solve the problem as soon as possible day and night. Solve problems for me, and I have been praised by leaders in my work many times. In 2019, we purchased the 890 Titrando moisture analyzer. This instrument, which does not need to be connected to a computer, is as stable as ever, and its compact body solves the problem of difficult placement in my experiment. Over the years, I have been purchasing some things from Metrohm intermittently, such as electrodes, exchange units, etc., because the products are worthy of my trust, and the timely reply of the engineer has added points to my trust in you. The next step is 2023. Add a cassette furnace to the 890 to optimize our moisture analyzer. 我们单位早在2003年就和万通仪器结下了缘分，最早使用了785电位滴定仪，后来我在2014年我又采购了888DMP全自动电位滴定仪，至今又陪我至今8个年头了，和我一起奋战在养殖投入品质量安全控制的第一阵线，就算超负荷运行，总是能稳定的出来数据，重现性优秀，偶尔遇到点状况，你们的工程师总能不分昼夜的尽快的给我解决问题，使我多次工作中得到领导的表扬。2019年我们又采购了890 Titrando水分测定仪，这个不用连接电脑的仪器一如既往的稳定，小巧的身躯更是解决了我实验里摆放困难的问题。这些年，一直在断断续续的采购万通的一些东西，例如电极、交换单元等，因为产品值得我的信赖，工程师的及时回复更是给我对你们的信赖加了分，下一步我计划2023年在890基础上加一个卡式炉，优化我们的水分测定仪。"

"作为使用者，很满意万通915的水份仪；操作使用、维护很方便，并且运行很稳定，非常好。现在实验室有2台915的水份仪，用了3年多了，没有出现过停机的故障，很满意。 另外有一个小瑕疵我需要提下：我们的2台915在运行过程中会出现一种状况，就是突然停在某个步骤界面，不会进入下一步，关机按钮也不起作用，只能拔掉电源。这种情况可能1、2个月出现一次；据说是中英文系统兼容性的问题？，希望后续能解决，不算很大的问题，但是感觉很不好。 As a user, I am very satisfied with the moisture meter of Metrohm 915; it is easy to operate, use and maintain, and the operation is very stable and very good. Now there are two 915 moisture meters in the laboratory. It has been used for more than 3 years, and there has been no downtime. I am very satisfied. There is another small flaw that I need to mention: our two 915s will have a situation during operation, that is, suddenly stop at a certain step interface, will not enter the next step, and the shutdown button will not work, you can only pull it out. Power down. This situation may occur once in one or two months; it is said that it is a problem of the compatibility of the Chinese and English systems? , I hope that it can be solved in the follow-up. It is not a big problem, but it feels very bad."

"We are using the Metrohm IC for method development for Cations and Anions. Yes we can achieve reproducible results using Metrohm IC. Training on method development and new applications will help us to increase our usage."

"We gave been using this instrument for the last 15 years. It is giving great results with accuracy with low maintenance cost. We have also maintenance contract with Metrohm. Their engineers very friendly and co-operative. Cost for AMC contract is also reasonable."

"The instrument feels good "

"This device makes it possible to eliminate the operator effect on the measurement which is a significant gain. It allows us to reach extremely low concentrations which is a strong asset. We are quantifying halogens in different matrices and so far the results are promising. We use the device non-stop, which allows us to take a large number of samples, but we have noticed mechanical problems with the autosampler or the 10-way valve (perhaps there are parts that need to be repaired or changed during maintenance). The problems have been solved thanks to Metrohm France's after sales service. One area for improvement would be to be able to quantify nitrate and nitrite ions via combustion."

"Very robust equipment, easy to use and very precise. "

"It is an instrument that does not give problems, the more it is used the better results it gives."

"Results obtained with CIC are accurate and precise. Only milli-q water required for analysis so it's environmental friendly and cost effective. Quick analysis, no sample preparation required. Very rare that maintenance is required, and also very quick support from service person."

"Good instruments"

"Its very good and easy to use."

"Far better than other manufacturers of ion chromatography equipment."

"Instrument of high precision and reliability, despite hostile materials."

"The analytical technique is effective for our applications; in particular in the determination of levoglucosane which, according to the literature, it is not easy to obtain adequate resolutions on environmental samples if adequate products are not available; Metrohm's service is always punctual and attentive, the operators kind and prepared. However, some instrument care is required to maintain the stability of the chromatogram."

"We have done an upgrade of our current IC 940. This enables us to independently run two different methods, using two different eluents, columns, temperatures, flows and sample dilutions. The results are what we expected, as we speak about the upgrade and not a whole new device. Performance is great, repeatability and reproducibility as well."

"The instrument is very useful in the area of extractables and leachables. We analyzed the anions present in sample matrices. The instrument accuracy and reproducibility is good."

"User friendly and results are reproducible. One can analyse the many different electrochemical aspects of electrodes."

"We gained time in analysis because of the responsiveness."

"It is robust, trustworthy analitycal equipment. Day after day it meets our expectations."

"It's an easy-to-use product, at least for me, I'm already used to working with Metrohm chromatographs. Value for money could be better. We are still testing, but the results are good. I think it was a good acquisition. I can not report further on the analysis, but It was used for determination of chloride in petroleum derivatives."

"The equipment has a great performance for the analysis of ammonium in tobacco. I need to upgrade to meet ISO 21045."

"This instrument is a combination of oxidative furnace and ion chromatography. Furnce is from Analytik Jena but the instrument operates one software from Metrohm. Analysis takes 30 minutes to complete and it is almost interference free."
