| Tidying Up An Analoy 1401 Alloy Analyser |

Thanks Phil, I've ordered some but goodness knows when or even if they will arrive in these strange times we live in - at least if they are the purity that they claim contaminants won't be a problem. Graham when I first got the Analoy's I thought about de-compiling the firmware - I've done quite a bit of 8085 coding in the past, but it's actually quite a daunting task going from binary with no idea what does what to a sensible assembler listing with meaningful labels. In fact it's rather like the 'Step 5' code for the Beaver TC20 lathe PLC that I did and took WEEKS over, but with rather less clues ! Though I guess there is a table embedded in there somewhere mapping 'CCD element' output to detected metallic element. |

I think getting reasonably high purity graphite will solve the problems. |

I'm hoping so Steve, but that's a few weeks away as the graphite is on the classic 'slow boat from China' - probably as well as I'm getting too many projects all running concurrently :med: When doing soil sampling you mix it up in a jar, give it a shake and leave it to settle for a few days, and the differing particles settle out in distinct layers giving a good idea of composition. I did wonder if I ground up a few of the used electrodes in a pestle and mortar with water and left them to settle it might reveal something, but being such a small sample would need to be in something like a small test tube. Where the heck are my small test tubes :scratch: |

Carbon electrodes for welding or arc gouging might be easy to get and shouldn't have funny stuff in them. Sent from my SM-G892A using Tapatalk |

But not 3 mm diam I think ? |
