Testing Gold Buyers and Teaching Sellers

Testing Gold Buyers
Gold sellers are getting smarter and have more options on where to sell then ever before…Agreed?

A recent news story shows the number of options that sellers have and highlights the range of payouts that gold buyers offer
(News Report Video Link).

People selling gold are going to be more aware of the options they have and shop around more…and they may start looking for buyers that use x-ray fluorescence technology.  We have seen reports like this before and this one features the Quickshot XRF QSX-295Tplus.  The user of the system pays out based on the highest accuracies and has earned a reputation for his payouts based on XRF…this reputation and the ‘word of mouth promotion’ has helped him increase his gold buying profits substantially.

Let us know…
     Have you noticed more sellers collecting options before selling?
     Do you use x-ray fluorescence so that the seller feels they are getting the best option?
     Are gold sellers more aware of who they are selling to and getting the best value?

Quickshot XRF offers several analyzer options for verification of gold and other precious metals.  From “entry level” systems to refiner quality analyzers, we can discuss what is critical to your business and offer options to help increase profitability through reputation.

Evolution of Gold Buyers; Moving to Pin-Dips for Instant Assay

One of the most common applications of Quickshot XRF analyzers is the accurate quantification of gold and other precious metals.  Having provided solutions to this industry since our first days, we have seen the increased number of gold buyers and the evolution of many.  That evolution will typically develop from using simple karat identification tests (acid tests, etc) when purchasing scrap to utilizing the benefits that x-ray fluorescence technology offers in speed, accuracy and reliability.  The next phase of evolution is when a buyer that began with a focus on just gold content realizes the need for high accuracy on all precious metals – something that XRF can provide.  Whether the interest is just gold or additional precious metals, many buyers will begin melting goods into bars before sending to the refiner and some have actually evolved into refiners.

Gold Bars Tested by XRFWhen clients reach the point of melting down scrap, they will sometimes request consultation on the best methods of precious metal assay.  The experiences staff of Quickshot XRF can assist with a discussion on various approaches to maximize the accuracy of x-ray fluorescence.  One of these methods involves creating pin-dip samples for instant assay; which is a practice used by precious metal refiners as well as gold buyers that melt down scrap.

Instant assay of precious metals and karat alloys uses the XRF technique that requires the samples be very homogenous (uniform throughout) in order to achieve the highest accuracy.  Homogenous is an absolute requirement.  If molten metals are allowed to cool down slowly they usually segregate, or separate, into non-homogenous materials – the outer surface often being richer in gold if it is a karat or scrap.  This affects the accuracy significantly since all XRF analyzers measure only 10-25um into the surface of a sample.  Molten liquid metal is very homogenous if stirred and mixed.  When the molten metal is quickly quenched, or cooled, the uniform distribution of the elements in the liquid metal state is “captured” better and retained in the resulting solid form.  Use of hollow vacuum-evacuated glass tubes, called “pin dip tubes”, facilitates taking proper samples for the instant assay.

QSX Instruments Inc: Interview

Quickshot XRF Founder
Scott Kramer is more than the Director of Sales and Marketing at QSX Instruments, Inc – he is also a founder of the XRF Sales company.  His career began over twenty years ago as a sales and service technician for an industry leading manufacturer.  QSX Instruments is the second successful organization he has started that focuses on X-ray Fluorescence technology and the solutions it provides.  Scott has a hand in every aspect of the organization and we were able to discuss a few topics with him here…

The first quarter of 2012 has been the most successful one in the history of QSX Instruments. 
What do you credit that to?
It is the type of quarter we expect at this point.  We offer a great product and our after the sales service/support is second to none, eventually word gets around.  Plus, the cost for a good performing XRF has always been too expensive for most of the smaller companies but our line seems to meet that need.

The Quickshot XRF line has focused on precious metal identification solutions – but what other applications are you most excited about the lines abilities in?
RoHS testing applications.  Offering both handheld and desktop systems for this interest lets us speak to the benefits that each model provides and suggest the best fit for a potential end-user.  When looking at the desktop system, the low cost Si-PIN system provides excellent results for RoHS screening needs while the SDD version reduces the measurement time by about 3/4 less but with top accuracy.

Looking at gold testing solutions; the line includes a handheld system but desktop models are the first suggestion.  Why is that?
The handheld systems work well for what they were designed for, portability and field use.  We find that many gold buyers use the ‘x-ray guns’ positioned so that the beam is pointed upward and they place parts on the nose of the gun.  This method works fine, but radiation may be emitted unless they have a part that is flat, thick enough and totally covers the aperature of the unit.  We sell bench top models for about the same cost and they emit zero radiation because the part is placed inside a chamber and the analyzer will not operate unless the door is closed.  Additional benefits of the desktop models are the streamlined software with excellent report generation, and the potential cost of ownership advantage that comes from a system operating at 1/10 its max power compared to a handheld that must run at max power to obtain similar results.  Gold buyers need to consider the long term benefits of the investment and I have asked our sales staff to provide information for them to consider.

What is your favorite Quickshot XRF analyzer?  Why? 
The newest analyzers; the QSX-295Tplus and QSX-82D.  These instruments are well thought out designs with specific goals in mind.  The speed and accuracy offered should make it hard to choose any other products.

What changes stand out from your twenty(plus) years involved in XRF?
Well, all the obvious answers apply here…greater range of applications, faster measurement speeds, the introduction of field portable systems (handheld XRF) and software design.  I am most proud of the Quickshot XRF software packages which our clients consistently note as being streamlined and simple to navigate.

How do you see the remainder of 2012 for Quickshot XRF?
We look forward to continuing the upward trend that we are on; thanks in large part to our satisfied clients telling their peers about the solutions we offer.  However, we are also excited to broaden our application reach with the handheld system and some potential new releases. 
Stay tuned; we are excited and we believe people interested in XRF will be as well.

RoHS2 and XRF Technology: Article from PCB Magazine

With the RoHS2 regulations, we have seen a renewed interest in X-ray Fluorescence technology for hazardous substance testing.  Many organizations involved with electronic components, circuits boards, etc are affected by these regulations are looking to XRF analyzers as part of their compliance system.

In the February issue of ‘Printed Circuits Design’ Magazine, an article discusses the technical documentation and process control aspects that must be considered.  The article, written by Scott Mazur, highlights XRF Technology for an organizations internal process control and as an RoHS2 monitoring device.  He notes, “During electronics manufacturing, many variables and cross-contamination opportunities exist.  XRF technology can verify that the various processes, equipment, tools and materials are compliant.

It is a beneficial read for organizations considering their approach to RoHS2 monitoring and control.

He highlights the portability benefit of Handheld XRF, which will allow for on site vendor audits.  The following manufacturing areas being potential XRF testing points:
-  Surface Mount Technology
-  Wave Solder
-  Hand Soldering
-  Final Assembly

While the author does highlight Handheld XRF for its portability, we always suggest that organizations dealing with smaller components and looking for streamlined functionality consider the QSX-82D desktop model from Quickshot XRF.  Please contact a QSX Instruments associate to discuss your process control requirements and how the technology may best fit…and read that article.

Gold Testing XRF Step Into 2012 With New Software

As we enter the New Year, QSX Instruments Inc is very excited to release a new software package for our popular X-ray Fluorescence analyzers.  A focus during the last quarter of 2011 was to complete the updated software package for QSX desktop systems built for detecting gold and other precious metals – the QSX-79T, QSX-79Tplus, the QSX-295T and the soon to be released QSX-295Tplus.
