Looks like the news leaked out, as the stock has risen in the past few days. It appears we will need a some volume to push above 3 3/4, which is the 50-day moving average as well as the peak during the aborted January Effect rally). My cost basis is still not in sight. -g- Tom

Pittcon '98: pubs.acs.org Sensar introduced the Series 3000 chromatograph (circle 203) for supercritical fluid chromatography (SFC). The system was designed for the petroleum industry to use in monitoring the quality of diesel and jet fuel before shipment to customers. Provo, Utah-based Product Manager W. Dale Felix told C&EN that California now requires use of a method-ASTM D-5186-that specifies SFC in analyses of the aromatic contents of diesel and jet fuels. He added that the method is being considered by other states and by regulatory agencies and that the Series 3000 meets the method's requirements. The Series 3000, listed at $40,000, consists of an oven module with injection system, a flame-ionization detector, and a pumping system. Options include a $5,000 data-collection package and a $7,000 autosampler. --------------------------------------------------------------------------- The explosion of mass spectrometric detectors for LC continues, as is evident from the bewildering array of offerings at Pittcon '98. And time-of-flight (TOF) was the buzz. TOF detector technology has several advantages, explained Lance C. Nicolaysen, director of marketing at Micromass, Beverly, Mass. Scanning speeds are usually 10 times faster and sensitivities are 10 to 100 times greater than with quadrupole technology. The detectors are rugged because they have no moving parts, requiring very few adjustments and no tuning. "Calibration is rock steady and it's just much easier to use than quadrupole" technology, he said. Sensar launched the Jaguar benchtop TOF MS instrument (circle 219), featuring an ESI interface. Jaguar can acquire 5,000 spectra per second and continuously store up to 50 spectra per second. Patented ion optics and acquisition electronics enable detection limits as low as 10 attomoles. The $147,000 list price includes data-processing software. Tom
