SynChropak Propyl is designed for hy drophobic interaction chromatography of proteins. Chromatograms are differ ent from those obtained by reversedphase chromatography because the eiutlon orders are different, and small changes in the hydrophobic arm affect retention. Mild eiutlon conditions at neu tral pH and the absence of organic sol vents preserve enzymatic activity dur ing analysis. Synchrom 421
Chrysotile Asbestos SRM 1876 is certified for the number of chrysotile fibers/0.01 m m 2 of filter area and intended for use in evaluating tech niques used to count and identify as bestos fibers on filter paper by trans mission electron microscopy. It should also be useful in evaluating sample preparation as described in the EPA method for measuring asbestos in air. NBS 422
Laser Dye Dye 26 is a photostable IR laser dye with a tuning range that extends into the high-transmission region of optical f i bers. With a mode-locked Nd-YAG laser at 3 Hz and with picosecond exci tation, the dye is tunable between 1.15 and 1.24 μΓη. Pulse durations are 21 ps and 5.5 ps for pump and dye laser pulses, respectively. Kodak 423

Fill a Staff Position on Capitol Hill Two ACS Congressional Fellowships Available To Begin Fall 1984 The objectives of the fellowship program are: • To provide an opportunity for scientists to gain firsthand knowledge of the op erations of the legislative branch of the federal government, • To make available to the government an increasing amount of scientific and technical expertise, and • To broaden the perspective of both the scientific and governmental com munities regarding the value of such scientific-governmental interaction.
Applications should be submit ted by January 31, 1984 to: Dr. Annette T. Rosenblum Department of Public Affairs American Chemical Society 1155—16th St., N.W. Washington, D.C. 20036
Applications consist of a letter of intent, resume, and two letters of reference. The letter of intent should include a description of the applicant's experience In publicoriented projects in which scientific or technical knowledge was used as a basis for interaction and a statement that tells why they have applied for the Fellowship and what they hope to accomplish as an ACS Congressional Fellow. The resume should describe the candidate's educa tion and professional experience and in clude other pertinent personal informa tion. Letters of reference should be so licited from people who can discuss not only the candidate's competence but also the applicant's experience in publicoriented projects. Arrangements should be made to send the letters of reference directly to ACS. For further information call (202) 872-4384.
