Zagadnienia automatyki, pomiarów i sterowania projektowanych lub modernizowanych urządzeń linii produkcyjnych lub całych wydziałów produkcyjnych rozwiązywane są w Bipromet S.A. na bazie sterowników programowalnych firm SIEMENS, MODICON, TELEMECANIQUE, G.E. FANUC i OMRON. Uruchomione systemy nadzorowane są przez stacje operatorskie z oprogramowaniami UNICELL, COROS, FIX InTouch i ASIX. Z wielu dużych aplikacji zaprojektowanych, oprogramowanych i uruchomionych przez Bipromet S.A., w artykule opisano: instalację przetłaczania i utylizacji gazów konwertorowych HM Głogów, Oddział Pieców Szybowych HM Głogów, Oddział Pieców Szybowych i Wydział Przygotowania Wsadu HM Legnica, Oddział Rafinacji Cynku HC Miasteczko Śląskie, Wydział Pieców Anodowych HM Głogów. Dotychczasowe osiągnięcia zaświadczają o tym, że jedną ze specjalności Biprometu jest rozwiązywanie szeroko pojętych problemów automatyki, sterowania i nadzoru nad procesami technologicznymi na najwyższym poziomie światowym.

The problems of automatics, measurement and steering of the designed and modernized installations of the production lines or whole production departments are solved in Bipromet S.A. on the base of programmers of the firms: SIEMENS, MODICON, TELEMECANIQUE, G.E. FANUC and OMRON. The started systems are supervised by operator-stations with software UNICELL, COROS, FIX InTouch and ASIX. Great applications described here, some from among many, programmed and set working by Bipromet S.A., are: installations for pumping and utilization of converter gas in HM Głogów, the Shaft Furnaces Plant and the Charge Preparation Plant HM Głogów, Zinc Raffination Plant Miasteczko Śląskie, Anode Furnace Plant HM Głogów. The attainments of Bipromet, up to the present, testify that solution of the problems of automatics, steering and supervision of technological processes is one of its specialities, up to the highest world standard.

Three different mass spectrometric method suitable for the analysis of polyprenyl and dolichyl phosphates and their glycosylated forms are described. Fast atom bombardment mass spectrometry (FAB MS) of glycosyl monophosphopolyprcnols produces negative ions characteristic of the intact molecule. Tandem mass spectrometry of (M-H)~ anions allows the determination of masses of both glycosyl and lipid moieties. Thus, for example, FAB-MS/MS of a mixture of native glycosyl monophosphopolyprenols isolated from ethambutol-treated Mycobacterium smegmatis enabled us to detect two novel pentosyl monophosphopolyprenols. Two other methods are proposed for the analysis of prenyl phosphates, as these compounds do not produce fragments in FAB-MS/MS at low collisional energy. By Desorption Electron Impact ionization (DEI) an intense (M-H3PO4)* ion as well as fragments corresponding to the successive loss of isoprene residues (68 Da) can be observed. Alternatively, Desorption Chemical Ionization yields ions corresponding to the loss of 66, 78 and 98 Da (i.e. of a part or the entire phosphate moiety) of a prenyl phosphate molecule. Tandem mass spectrometry of the (M-H-98)" ion gives a series of intense fragments differing by 68 mass units over the whole mass range.

A Berner cascade impactor was used for the separation of solid urban aerosols in two localities of the Baltic coastal macro-region - Słupsk and Hel - in different seasons and weathers. Ten ranges of aerodynamic diameters between 0.009 and 8.11 žm were used. The elementary composition for each diameter was obtained in a complex procedure consisting of laser ablation of deposits, then their successive ionization in an inductively coupled plasma generator, and finally, mass selection in a quadrupole spectrometer. Despite its complexity, the chemical element analysis method proved to be versatile, allowing the identification air pollution from natural and industrial sources, and road traffic.
