Can Your GC Analyze Solids? It Can With A Pyroprobe®. The Pyroprobe expands the capabilities of your GC, GC/MS or GC/IR by allowing you to analyze most solids including synthetic polymers, geo-polymers and biopolymers. And that's not all. A Series 120 Pyroprobe can perform: • Analytical Pyrolysis • Headspace Analysis o f Volatile Organics • Simulated C o m b u s t i o n Studies • Simulated Thermal Analysis
Pyroprobe®... The Solid Solution
New Products pH Gradient Scanner Model 240 pH scanner automatically scans the pH gradient of an electrofocusing gel in approximately 10 min. The automatic feature eliminates errors that may arise from hand measurement in consistencies, electrode drift, or time variations. Tedious slicing and soaking of gel sections before measurement are unnecessary. Bio-Rad 419
Mass-Selective Detector Model 500 Continuously Variable Angle Specular Reflectance Accessory is for use in IR spectroscopy with both dispersive IR and FTIR instruments. It covers a range of angles of incidence from 20° to 89° by a simple rotation of the sample around a transferred focal point. Increased range is achieved by a switch of a sample with one mirror, yielding a range of 1-89°. Barnes Analytical 404
HP 5970A MSD detector, for specific and selective sample-component identi fication, interfaces with most capillary GCs. It confirms the presence of an analyte through spectral acquisition when used in qualitative analysis. With the advantage of its selected-ion-monitor ing software, it monitors up to six ions with a high degree of specificity. Hew lett-Packard 421
Data Acquisition System
Lab Interface
DT4136 Lab-Datax system takes up to 17.8 million analog data points to disk storage at 96 kHz without the loss of a single data point. The system features interface design for high-speed DMA data transfers, software designs for de vice handlers, and a Winchester disk drive optimized for throughput. Data Translation 417
Universal Interface is a data acquisition system that can acquire, digitize, and store data from most analytical instru ments. It has two analog and eight dig ital input channels through which data can be acquired at variable rates, from 100 μ s to 6 s per data point. Data can be displayed on a CRT either in real time or from the interface's 64K memo ry. Varex 422
DNA Purifying Column Elutip-d column provides a method of simultaneously purifying and concen trating DNA. The column attaches to the end of a syringe, DNA is adsorbed to the matrix in the column, allowing particu lates and contaminants to be washed away by a buffer solution, DNA is then eluted with as little as 0.4 ml_ of buffer, with recoveries as high as 95 % .
