Vacuum Filter Chemistry
- In chemistry and common usage, a filter is a device (usually a membrane or layer) that is designed to physically block certain objects or substances while letting others through.
- A space or container from which the air has been completely or partly removed
- A space entirely devoid of matter
- the absence of matter
- void: an empty area or space; "the huge desert voids"; "the emptiness of outer space"; "without their support he'll be ruling in a vacuum"
- A gap left by the loss, death, or departure of someone or something formerly playing a significant part in a situation or activity
Filters and Filtration Handbook, Fifth Edition
Filters are used in many industries, especially the water,sewage,oil, gas, food and beverage, and pharmaceutical industries. This new edition of a well-established title retains the aim of being a practical account of filtration equipment and its applications. The previous edition is badly out of date, and Ken Sutherland has completely revised and re-written it, changing emphasis and content wherever necessary. It remains an essential book for the engineer working in a plant situation, who requires guidance and information on what is available and whether it is suitable for the job in hand.

Geez, what a mess. I have no idea what course this lab was for, but I'm pretty sure it wasn't for one I was taking. It looks like a chemistry rig, but the interior looks more like the biology department than anything in the Chemistry Building.
(Addendum 7/20/08) Hmmm... I just noticed that the fluorescent desk lamp on the bench is either mine or is exactly like one I had (and still have). There are also some photographic filters on the bench next to the Erlenmeyer flask, and they look suspiciously like the ones I had. So maybe this was my mess in fact. Ugh. No wonder I blanked it out!
At this point, I'm thinking that this is a lab in the basement of the Chemistry Building, and this was the setup for my DI on crystal growth in gels.
A DI, or Directed Inquiry, was an individual study project undertaken by a single student under the tutelage of a faculty member. They were a notorious refuge for slackers during the Third Term, a six-week academic period in the spring at the end of the year, when the regional weather is at its best, the outdoors beckon, and the young man's (and presumably young woman's) fancy lightly turns to thoughts of love. Third Term is no more, but do they still have DI's? For that matter, do they still have love? I sure hope so, because that's the single best thing about going off to college!

What a view this was taken from the Eastbourne Pier, towards King Edward's Parade, captured using the polarizing filter, the best filter I have.

A multidisciplinary approach to understanding the fundamentals of mass spectrometry for bacterial analysis
From chemotaxonomy to characterization of targeted proteins, Identification of Microorganisms by Mass Spectrometry provides an overview of both well-established and cutting-edge mass spectrometry techniques for identifying microorganisms. A vital tool for microbiologists, health professionals, and analytical chemists, the text is designed to help scientists select the most effective techniques for use in biomedical, biochemical, pharmaceutical, and bioterror defense applications.
Since microbiological applications of mass spectrometry require a basic understanding of both microbiology and analytical chemistry, the editors have incorporated material from both disciplines so that readers from either field will come to understand the necessary principles of the other. Featuring contributions from some of the most recognized experts in both fields, this volume provides specific examples of fundamental methods as well as approaches developed in the last decade, including:
* Metastable atom bombardment pyrolysis mass spectrometry
* Matrix-assisted laser desorption/ionization mass spectrometry (MALDI)
* MALDI time-of-flight mass spectrometry (MALDI-TOF MS) of intact bacteria
* High-resolution Fourier transform mass spectrometry (FTMS)
* Electrospray ionization (ESI) mass spectrometry
Identification of Microorganisms by Mass Spectrometry represents the most comprehensive and up-to-date work on the topic currently available. It is liberally illustrated with figures and tables and covers every aspect of spectrometric identification of microorganisms, including experimental procedures, various means of sample preparation, data analysis, and interpretation of complex mass spectral data.
