Many of you who are involved with PMI (Positive Metals Identification) will already have handheld XRFs. These are (depending on their age) generally excellent for the analysis of transition and heavy metals, and combined with their portability and ease of use, have been the instrument of choice for a long time. However, there are a few scenarios where they come up short such as:
- Analysing carbon in steels
- Distinguishing L & H grade stainless steels
- Determining carbon equivalents for weld repairs etc
The SciAps Z-901CSi
Recently, SciAps launched the Z-900 series handheld LIBS analysers which built on the success of the Z-200/300 series LIBS which included the Z-200C+, the first handheld LIBS to be able to measure carbon in steels with the sensitivity to be able to distinguish the difference between such things as 316 and 316L stainless steel.

The Z-901CSi, one of the models in the new range is dedicated to measuring carbon and silicon. This makes it the ideal complement to your existing handheld XRF. It’s compact and portable nature mean you can easily add it to your in-field kit bag, use your handheld XRF for measuring all the metal elements and then shoot the same sample with the Z-901 CSi and a few seconds later have your carbon and silicon analysis.
Being able to do all this in-field certainly beats having to collect samples and take them back to the lab and then measure them with a spark-OES, especially when you can get the same level of accuracy from a handheld instrument!
For more information about how XRF and LIBS complement each other pleaser refer to Positive Metals Identification PMI – XRF vs LIBS.
In a Nut Shell
- The perfect complement to handheld XRF
- Measures C + Si in steels, L-grade & H-grade stainless
- Ultra compact at less than 2kg, it handles like an XRF
- Runs on Android
- Accepted test method by the American Petroleum Institute (API 578 2nd Edition)
Who will the Z-901 CSi Suit?
The SciAps Z-901 CSi LIBS for carbon and silicon is an economical companion for XRF users who need to add carbon to their analysis. Ideal for:
- PMI practitioners who use XRF every day in field needing to supplement XRF data with carbon on occasion
- Those who use XRF but need to farm out carbon analysis to spark OES
- Pipeline engineers who only check the carbon equivalents. Their XRF already identifies tramp elements and residuals much easier. Adding SciAps Z-901 CSi completes the picture and meets multi-test averaging protocols required by some refineries and pipeline operators.
- Inspection companies
- Fabricators needing to differentiate L and H grade stainless steels
- Anyone doing silicon surveys: 650 refineries worldwide; adding LIBS in 939C
- HF Alky units
- Cast iron customers
If your handheld XRF is getting on a bit and takes a while to complete measurements, it might be tme to put it out to pasture. In such an event, you might want to consider the Z-902 Carbon which measures pretty much all the alloying elements you will commonly encounter as well as carbon.
The Ultimate in Versatility
For the ultimate in versatility and for the most comprehensive analysis, there is the One Box. This solutions can combine any of the SciAps LIBS and XRF systems into a single, weatherproof case for ease and transportability. Weighing in at about 10kg, this package will easily travel with you to the most remote or difficult to get to scenarios.
In case you aren’t familiar with LIBS (Laser Indusced Breakdown Spectroscopy), it is very similar to spark OES, differing mainly in that it uses a laser as opposed to an electrical spark to vapourise a tinty amount of your sample to be analysed. The main difference here, is that lasers are so small, that the whole LIBS device can be made into a small handheld device like your handheld XRF. The same is not possible for spark OES, which can be made portable, but still weigh tens of kilograms and require a trolley to move them around.
