Hi Jerry,
I recommend Titanocene dichloride reduced with Zinc powder. It is a typical indicator for detecting water and O2 in the Glove box. It is said to be < 5ppm of O2. Here are some references, but there should be more literature. https://urldefense.us/v3/__https://pubs.acs.org/doi/abs/10.1021/ed053p110__;!!G_uCfscf7eWS!cVNwfsj3NCYMeMqJY8QwR-yTjt8OPHb_oPIT_xJmV-66dPX4wMlsEotqxv9pAoZeBcHmeShK4ebCU-zwVmHYRmkQIqz9v7pFlpbC2umz5JB6blQ$ https://urldefense.us/v3/__https://pubs.acs.org/doi/pdf/10.1021/ed075p460__;!!G_uCfscf7eWS!cVNwfsj3NCYMeMqJY8QwR-yTjt8OPHb_oPIT_xJmV-66dPX4wMlsEotqxv9pAoZeBcHmeShK4ebCU-zwVmHYRmkQIqz9v7pFlpbC2umzXOanahY$ Regards, Ryuichi Ryuichi Shimogawa, Ph.D. Visiting Scientist Department of Materials Science and Chemical Engineering Stony Brook University Stony Brook, NY 11794 Email: ryuichi.shimog...@stonybrook.edu Tel: +1 (631) 690 5235 Visiting Scientist Structure and Dynamics of Applied Nanomaterials Group Chemistry Division Brookhaven National Laboratory Email: rshimo...@bnl.gov On 2/21/24 17:38, ifeffit-requ...@millenia.cars.aps.anl.gov wrote: > Send Ifeffit mailing list submissions to > ifeffit@millenia.cars.aps.anl.gov > > To subscribe or unsubscribe via the World Wide Web, visit > https://urldefense.us/v3/__http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit__;!!G_uCfscf7eWS!cVNwfsj3NCYMeMqJY8QwR-yTjt8OPHb_oPIT_xJmV-66dPX4wMlsEotqxv9pAoZeBcHmeShK4ebCU-zwVmHYRmkQIqz9v7pFlpbC2umzJVB5ZMw$ > or, via email, send a message with subject or body 'help' to > ifeffit-requ...@millenia.cars.aps.anl.gov > > You can reach the person managing the list at > ifeffit-ow...@millenia.cars.aps.anl.gov > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Ifeffit digest..." > > > Today's Topics: > > 1.
