Should I turn my analyzer off or use standby mode when not in use?

If you plan to run your analyzer daily, please keep it on at all times.

If you plan to run it a few times a week, please use the standby feature.

If the instrument will be off for a prolonged period of time, please contact XOS Technical Support at support@xos.com to discuss what is best for your situation.

How much radiation am I being exposed to?

Our products conform to all applicable Standards under 21 C.F.R. Chapter I, Subchapter J. Each analyzer is delivered with a radiation survey report that summarizes the radiation emission testing performed at the XOS factory before shipment; this ensures that any leakage is well below regulatory limits. Each survey is serial number-specific, displaying the results from a particular instrument’s radiation emission test. You can obtain more copies of this report by contacting XOS at 518-880-1525 or support@xos.com. The analyzer should be surveyed annually by appropriate radiation safety personnel or qualified outside contractor, and operated according to all local, state and federal laws.

How often should I change my fan filter?

While there is no set time, please wash or replace your filter if it becomes noticeably dirty. This dirt can cause less air to flow into the unit and the tube may become too hot.

What is 2622, and do I need to use it?

2622 analyzers measure the background counts of the unit before measuring the sample itself. This allows for a more accurate reading to be given. This may be required depending on your regulations. Please contact XOS Technical Support at support@xos.com for more information.

Related Families

Do I need to vent my samples?

Yes - the main concern is if you are running samples that can expand readily, such as isooctane. For more stable samples, it is not as large of a concern but is still highly recommended.

Related Families

What does 'venting' mean?

When using the standard XRF sample cups, the proper procedure is to “vent” the sample. This means to poke a hole on the back of the cup, allowing any vapors to leave the sample cup. Trapped vapors can cause bowing in the sample film, which can lead to irregular results.

How often should I get preventive maintenance done?

Preventive maintenance should be done annually to keep the unit in its best working condition.

What is the difference between a chemplex cup and an accucell?

Chemplex cups are composed of three parts: the sample cup, the sample film, and a retainer ring. The sample is placed in the cup and then the film is placed on top with the retainer ring being pushed down to hold it in place.

Accucells are essentially smaller, pre-assembled chemplex cups. The sample is inserted through a small hole on top of the cup. These do not need to be vented.

Related Families

Can I reuse a sample cup?

No, reusing sample cups and film causes contamination issues that will lead to incorrect results.

Related Families

What do I do if my instrument is not working properly?

If you are experiencing issues with your PPM readings, clean the sample area of the unit using high grade IPA and change the secondary window film, then try running the sample in a new sample cup and film. If the problem persists contact XOS Technical Support at support@xos.com.

For other issues please contact XOS Technical Support and if it is a fault please write down the exact wording on the screen. Let the Support member know of any other issues that you may be experiencing.

Do I need to pair the sample basket with the unit?

Yes - each sample basket is designed to a specific thickness to produce optimal counts for your unit. If you have more than one unit at your facility, it is extremely important that you do not swap the baskets. The serial number of the unit the basket is paired with will be engraved on the top.

What type of film do I need?

Different models require different film. Check your instrument manual to confirm which film you should be using on the sample basket and samples.

What is done during a preventive maintenance visit?

During a preventive maintenance visit, the following is performed:
1. Pump is rebuilt
2. Primary window and fan filter are both replaced
3. The interlocks and safety features are checked
4. Radiation survey is completed
5. Calibration is performed
6. The unit is given an overall inspection
7. Basic training on the unit can be provided

Does your optics suffer from radiation damage?

Not for a lab source. For synchrotron applications, no damage will occur from the incident beam as long as the optic is after monochromators.

Related Families

What is the typical lead time?

4-6 weeks for our optics. 6-10 weeks for our X-Beams.

Related Families

Can we get a DEMO optic to try out?

No, because the polycapillary optic technology and its benefits have been proven. The performance specs XOS provides in the quotation are based on the results from an XOS proprietary simulation tool and we guarantee those specs.

Related Families

Does XOS provide an optic alignment device?

Yes, we offer a custom solution dependent on the X-ray source.

Related Families

Can a Polycapillary optic work efficiently with my source?

It depends on the X-ray source characteristics especially the source size. If the source size is too large or the energy is too high the optic won’t provide any benefits.

Related Families

What is the largest output beam size for a parallel beam optic?

Currently 20mm, this is energy dependent. (low energy due to large capillary diameter).

Related Families

What is the smallest focal spot size you can achieve?

5µm at Rhodium Kα (20keV).

Related Families

What is the energy range of the optics?

10eV to 50keV. Most efficient at 5-10keV. Efficiency drops rapidly at higher energies.
