What maintenance intervals (calibration, electrolyte replacement) would you recommend for a pH electrode that is used very rarely, e.g. once a year?
@MetrohmTV 8 күн бұрын
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!

@MetrohmTV 8 күн бұрын
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
@MetrohmTV 29 күн бұрын
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?
@MetrohmTV Ай бұрын
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.

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!

How to fix blockage piston ? Tq im highly appreciate if u can reply
@MetrohmTV 6 ай бұрын
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 [email protected] 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?
@MetrohmTV 6 ай бұрын
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.

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
@MetrohmTV 10 ай бұрын
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

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.
