I have been thinking hard about going out sampling today, but in the end I decided to run the snow samples and blanks that I have collected so far in order to not fall behind with my measurements. After labeling and putting them out of the freezer for melting, I was running my morning routine.\n<\/p>\n
Today is \u00e2\u20ac\u0153Plane Day\u00e2\u20ac\u009d, so the base is a bit of a beehive. Around 11.30 I went outside to take photos of the plane touching down on the gravel runway – an impressive picture. Otherwise I was busy with measurements. I was running snow samples and standards to determine the retention time on the recently clipped column. I have prepared solutions apart from each other and in well ventilated areas in order not to introduce any contamination into the snow samples.<\/p>\n
After running individual compounds by injecting 0.5 \u00ce\u00bcL of headspace from the ampoule I mixed – so far – 9 standards in a common stock solution. I had problems with solubility in water, which I solved by adding ethanol. This worked fine. From this stock I will prepare
\ndilutions and set-up calibration curves for all compounds under investigation.<\/p>\n
I have also learned from the electricians that a new transformer will not be available until next week\u00e2\u20ac\u2122s flight. That means that the MOUDI will stay at the GAW Lab for the week and I will also move the bio-sampler and use it with the mains-powered pump (because the batteries are too short-lived, when it is this cold (currently -10\u00c2\u00b0C). For all other measurements I will stay at the (unheated) trailer.\n<\/p>\n
Not enough bad news today – the other truck broke down on the way back and will be out of service until at least next week. We now have to use the only (replacement) truck – Nuuk. That means rescheduling and I have set-up a regimen, where I will run the MOUDI & bio-sampler alternately overnight (which is fine – the longer the better). This way I can do my other tasks within approx. 4-5 hrs, which is also the usual timeframe for work at the lab. It now seems unlikely that I will sample regularly at the BAY site. With just one truck and being alone it will be difficult. Bear tracks have been found in the vicinity and going out without a vehicle is too risky.I finished \u00e2\u20ac\u0153early\u00e2\u20ac\u009d today – at 10.30 p.m.<\/p>\n","protected":false},"excerpt":{"rendered":"
