NO CHARGE? no problem for Zetasizer II In studies of flocculation and colloid stability, the region close to the zero point of charge is the most critical. It is in precisely this region of low mobility that other electrophoresis systems are least accurate and most difficult to use.
With its high frequency ^ ^ ^ optical modulator, the Malvern Zetasizer II solves this problem, allowing you to measure mobility and zeta potential with uncompromising accuracy right across the range. Measurements are simple, fast and operator-independent and Zetasizer II also gives you built-in submicron particle size capability.

News ests included problems in electrochemistry and mass spectrometry, and his work focused on theoretical development and applications of cyclic voltammetry, including computer modeling and computerized instrumentation. Nicholson's work in science administration has been widely recognized through numerous awards including, in 1982, the Presidential Distinguished Rank, the government's highest civil service honor.

use in undergraduate instrumentation courses. The subscriptions are intended to enrich the course content and encourage more students to continue their studies at the graduate level. Professors participating in the program are under no obligation except to ensure that the issues are available to students in the laboratory. However, many professors make special use of the issues by assigning student projects based on articles in the JOURNAL. Subscriptions begin with the September issue and end with the February issue. In addition to the copies of A N A L Y T I C A L C H E M I S T R Y , a guide is

Turi is special projects manager at Allied's Corporate Technology Center in Morristown, N.J., and is adjunct professor at the Polytechnic Institute of New York. Her main research field is the characterization of materials and the evaluation of the major parameters affecting their stability and processibility. Turi is the regional editor of the Journal of Thermal Analysis for the United States and Canada, the editor of a book entitled "Thermal Characterization of Polymeric Materials," and a past president of NATAS.

rolled in instrumental analysis courses in U.S. colleges and universities. This year, 769 six-month subscriptions will go to 298 schools participating in the Enhancement Program for Students in Instrumental Analysis Courses. This program originated from the Allerton Conference in 1981. The first year (1982) funding for the program was supplied by the ACS Corporation Associates. The Society for Analytical Chemists of Pittsburgh, one of the cosponsors of the Pittsburgh Conference, supplied the funding for this program in 1983,1984, and 1985. The program supplies copies of AN-

Unsolicited letters as well as a formal survey taken in 1983 attest to the value of this program from the standpoint of the professors. Professors who have not taken advantage of the program this year are urged to write the A N A L Y T I C A L C H E M I S T R Y editorial

Undergraduate Awardees to Receive ANALYTICAL CHEMISTRY The Division of Analytical Chemistry of the American Chemical Society has named the winners of the 1985-86 undergraduate awards in analytical chemistry. The awards, consisting of issues of A N A L Y T I C A L C H E M I S T R Y
beginning in October 1985 and ending with the May 1986 issue, are given annually to chemistry students at U.S. colleges and universities in recognition of outstanding scholastic achievement. This year's 394 awardees were chosen by the chemistry departments of their respective institutions. In addition to receiving the JOURNAL, student awardees will also receive the Analytical Division newsletter throughout the year. The undergraduate awards are
