if your question is about whether we can record "movies," the answer is yes. The new microscope at UofA is the Hitachi HF5000 - 200KeV aberration-corrected TEM, right? So, the only similarity is that both machines are probe-corrected STEM. The rest, from the manufacturer, are entirely different regarding stability, working voltages, EDS, and EELS capabilities. If you have more questions, please contact me at [email protected]. Thanks.

Hi, thanks for the visit and question. And yes, ABF is available at this equipment at ASU. Thanks.

@@marolgu Do you use beam stopper and STEM aperture 3mm to act as ABF?

We use a spectralon 99% reference on our instrument. Spectralon are calibrated references made of teflon. I have not used BaSO4 for baseline. If you are interested I see an interesting comparizon between references here: www.shimadzu.com/an/sites/shimadzu.com.an/files/pim/pim_document_file/applications/application_note/13902/a639_e.pdf

@@EyringMaterialsCenter Thank you very much. Have a nice day

Hi. If you are using Any Peak Force mode, the gains are being set automatically as you scan. In tapping mode they will appear on the Scan Parameters list of values to change.

@@EyringMaterialsCenter Thank you so much. 😃

Typically, you can set it and forget it! When using tapping mode, the setpoint can be decreased on samples that require greater tapping force. If your probe is tending to come off the sample surface, you should increase the tapping force. Also, make sure you're using the best probe for the sample.

@@EyringMaterialsCenter So Ideally, I can match the trace and retrace by changing the proportional and integral gains as pointed out in the video?

@@darylldalayoan4880 yes that is the goal to get good images.

Hi Sandeep, unless the offset is large I would not worry about entering a sample offset.

The standard TEM grid has a size of 3 mm in diameter.

Many thanks for your questions. Sample preparation is an important part of the microscopy experiments. 1. How long does it take to take a photo with an ETEM microscope? With you sample on a TEM grid, a photo can be taken within half an hour for sample loading and basic equipment check up. Then a single image only takes a few minutes to collect and record. 2. What if it is an aerosol sample? There is not much difference as long as your sample is on a standard TEM grid. 3. How to prepare an aerosol sample? Aerosol sample has to be collected in some way, say, on a filter paper. Then the sample can be moved from the filter paper to a TEM grid. You should search literature to find out the best procedure for this. 4. How do you get an aerosol sample into a cell? I am not quite sure about the "cell" you are talking about. You can send me an email to discuss about details.

All you would need to do is place the window in the beam path during the measurement. No special accessory is needed.

It is not recommended. A straight-through transmission if preferred. The ATR would only provide information about the surface of the material being analyzed.

Thankyou

Hi Manan, assuming the window is transparent enough, which should be the case, you can do a straight through measurement by mounting the window on the steel holder shown around 1:33 on the video. You can use tape to mount the sample as long as the beam does not go through the tape.

@@EyringMaterialsCenter is ATR required for this?

@@manojdhiman5694 I would not use the ATR for it unless you are only interested in analyzing the coating.

Hi Roman, The system owner should have access to doing that. Otherwise, I would suggest contacting PerkinElmer's customer service. Good luck!

Hi, Thank you for your interest. The proposed video is not currently on our list but it is an excellent idea and I will definitely keep it in mind for future videos.

Hi Partho, It is always a good idea to check where the laser spot is in relation to the white light coming from the camera before you insert your sample or probe. Using a white strip of paper, place it in the optical head just above the probe holder. It should be just to the left of or near center. The white light is your general field of view, FOV, when observing the live image on the software "Setup" screen. If you insert a very reflective sample, such as a smooth metal like gold, you can then direct the laser spot to the end of your cantilever. Make certain your probe is in the FOV, then focus on the reflective sample. Sometimes bringing the probe close to the surface of the sample will help in seeing the laser spot. Then watch the SUM. It should increase as the reflection of the laser hits the position sensitive detector. If you continue to have issues, feel free to connect with me on Zoom. I will be happy to walk you through the process. Best regards, Diana

@@dianaconvey4527 Thank You very much !

Luthfiyah, if I understand you correctly, I believe you are asking where to put a reference sample. The reference port is located on the front side of the integrating sphere. In the video you might notice there is a reference standard used on that port when a reference sample is not used. I hope this answers your question. ~Diana

Hi Neethu, The system is a dual beam instrument comparing the intensity between the 2 beams so there is no absolute measurement of the intensity only a relative one.

I see that you saw my response below. You might need to contact PANalytical for help they have excellent customer service.

I do not have the current price. Please contact the PANalytical sales office for pricing information.

how much was it ?

The issure can be a number of things. Make sure you have the PDF database on the computer you are using. If you are unsure of the elements present make sure they are selected in grey rather than green.

hi hasti have you solve the problem? i have the same problem as yours? by using the software ?

Hi thanks for your answer. I still have the same problem. I have PDF file on the the computer and I have imported them correctly because I can see the number of patterns which is a big one. but I still receive the same msg although I am sure about my the elements I chose

Hi how are u? I still have this problem:( did u find anything to solve it? let me know please and I will let you know too thanks

Hi Naresh, Please contact PANalytical, this program is sold by them.

HighScore Plus must be purchased from PANalytical.
