Metrohm product portfolio: A variety of robust and reliable instruments
Dr. Tröster, Head of the laboratory at MAN Energy Solutions, explains the impact climate protection regulations have on producers of gas and diesel engines for ships. Their engines can cope with different fuels, such as heavy oil, diesel or liquefied natural gas (LNG). In the future, methanol will play a key role providing new analytical challenges. MAN Energy solutions uses different instruments for quality assurance and control: titrators for standard parameters in fuels, Rancimat for oxidation stability measurements in biodiesel, and ion chromatographs for analyzing impurities in methanol.

What maintenance intervals (calibration, electrolyte replacement) would you recommend for a pH electrode that is used very rarely, e.g. once a year?
Hi This very much depends on the accuracy of the result you want to achieve. For example, if the result is only a rough guide, it is fine to perform a calibration or replace the electrolyte before the pH measurement. However, if you want the result to be as accurate as possible, maintenance is more important and should be carried out at least monthly or even weekly. In general, frequent maintenance of the electrode is recommended for warranty reasons and also with regard to the lifetime of an electrode.

Hi, our mining lab has just purchased an Eco Titrator 10080010 to be used for copper analysis via iodimetry. Can someone share a reference on how to set up the method using Eco Titrator? we have been using manual buret for iodometry, so this one is basically an upgrade. Thank you!
Hi Your local Metrohm subsidiary or exclusive distributor can help you with this! Have you been in touch with them?
On 913 with flexible sleeve how much electrode do we fill ? Thank you in advance
Hi If you're talking about electrolytes, the electrode should always be filled with electrolyte up to the filling opening, regardless of the type of Metrohm pH electrode. You can find more information on this topic in the monograph 81085081EN "pH Measurement" under "Electrolyte" and "Electrolyte Outflow": www.metrohm.com/en/products/8/1085/81085081.html
What if the blank read value of chloride.. Possible reason
We assume that you see a Cl peak in the blank. You could try increasing the rinsing volume. Or run several blanks in a row to see if the peak decreases. If yes, then increase the rinsing volume. If not, then it could be an impurity in the chemicals or the ultrapure water. Whenever possible, you should use chemicals and ultrapure water without impurities. Please also check our Product Help Center IC: www.metrohm.com/en/service/product-help-center/ion-chromatography.html

Why do I have to calibrate more often when performed at high temperatures? If I do it at 28 degrees Celsius, is calibration necessary every day?
We would recommend calibrating the sensor daily and at the temperature of the samples for exact results. It depends a bit on the accuracy that is required.

Muy buen video y lo explica muy bien.
Chú mình mua thuốc không nhãn mác , ko có hạn sử dụng , mình muốn hỏi mình có thể giám định thành phần thuốc này ở đâu ? Và chi phí giám định này cao ko ?
Một loại thuốc không nhãn mác, không hạn sử dụng sẽ không được lưu hành và khuyên cáo người sử dụng không nên dùng. Xác định thành phần thuốc rất khó khăn, phải dùng đến các loại máy phân tích hiện đại độ chính xác cao và giá thành rất đắt. Vì thế sẽ rất ít các cơ quan nhận mẫu kiểm nghiệm trong trường hợp này!
Fantastic system
Nice explanation 👌
Thank you 🙂
How to fix blockage piston ? Tq im highly appreciate if u can reply
Hi @fatinrun A blocked piston on an exchange unit is usually caused by a blocked tube or anti diffusion tip. We suggest: - Remove the anti diff. tip and try dosing again - If the anti diff. tip doesn’t rectify the problem then remove the burette tip and dose again - If the blockage still occurs then disconnect the outlet tubing from the valve unit and try dosing - make sure you have tissue at hand to catch the dispensed liquid - If problem remains then the issue has to be caused by a blocked valve/stop cock which will need removing/rinsing and potentially replacing - If this doesn't fix the issue, please send an email to technical@metrohm.co.uk and we will be happy to assist further.

Why is there moisture parameter in most of the analysis? How the quality is analyzed with moisture parameter alone?
Hi Moisture content is definitely one important parameter for the quality assurance, but it is not the only one. Next to that, multiple key parameters, like ethanol, glycerol, or active ingredients like sodium laureth sulfate can be measured simultaneously in less then one minute using the DS2500 Solid Analyzer. The Vision Air software displays all parameters on one screen when the analysis is finished.
Is it water they use to clean?
You should use distilled or ultrapure water for cleaning.
Is ASTM D1533 available with the same injection method?
Hi Thank you for your question. No, the oven method is not mentioned in ASTM D1533. It describes direct coulometric Karl Fischer titration. The samples must be added directly into the titration cell.

Great video 😊! Why only 4,7,9 buffers used for calibration! What is the maximum limit can dip the ph electrode or need to only dip the end of the electrode
Hi Samuel Thank you for your comment. You always have to calibrate with buffers which lie within your measuring range. With buffers pH 4, 7, and 9, you’re already covering quite a broad pH range. Should you need to cover an even broader range, you can use pH buffers from other manufacturers. As for the electrode: The electrode has to be dipped in in such a way that the diaphragm is fully covered by your measuring solution. I.e., the glass membrane and diaphragm have to be immersed but the electrolyte filling hole has to stay above the sample. Best regards Michel, Metrohm International Headquarters

Can i use optrode for turbidity titration(CTAB surface area method)
Hi We do have an application where we used the Optrode for turbidity titrations. However, turbidity titration does not work in every case. It depends on the difference of turbidity and on your sample. Therefore you would need to test it out for your specific application. Please find the application here: www.metrohm.com/en/applications/application-notes/aa-t-001-100/an-t-055.html If you need more support, feel free to contact your local Metrohm subsidiary or exclusive distributor: www.metrohm.com/en.html#country-selection Best regards Michel, Metrohm International Headquarters
Thank u for your kind rply. But in our case the end point is not capturing at the equivalnace point.(we are using optrode equiped with 905 titrando)
