The Agilent 7697A Headspace Sampler, in both 111 and 12 vial capacity configurations, represents the state-of-the-art in headspace gas chromatography. It is based on the architecture of the market leading 7890 Series GC and 7693A Automatic Liquid Sampler line of products.
Automatic Leak Check : Ensure each vial is leak free prior to analysis, no loss of precision or sensitivity
Alternate Carrier Gas Options: Safely work with hydrogen as a carrier gas to save laboratory cost
LECO’s CHNS-932 Elemental Analyzer is capable of determining the amount of carbon, hydrogen, nitrogen and sulfur present in a homogeneous aliquot weighing approximately 0.6–1.6mg (2.0mg maximum). An aliquot is weighed and placed into either a tin or silver capsule in which it is appropriately crimped. During the analysis, the aliquot is dropped into a furnace held at 1,000°C. At the same time the sample drops into the furnace, a dose of oxygen is released into the furnace. This causes the sample to readily combust forming gases of COX, H2O, N2, and SOX.
Know-how and ingenuity gathered from HORIBA air-to-fuel ratio measurement technologies used worldwide, to provide the highest level of performance.
This portable emission analyzer adopts this performance and adds original design for enhanced visibility and operation. A new sensor coefficient data memory function makes it possible to restore back-up data, providing faster start-up times and saving valuable operation time.
The LI-7000 CO2/ H2O Gas Analyzer is a high performance, dual cell, differential gas analyzer. It uses a dichroic beam splitter and two separate detectors to measure infrared absorption by CO2 and H2O in the same gas stream. At the heart of the LI-7000 is an innovative optical bench that can be dismantled and cleaned by the user without the need for factory recalibration.
The LI-8100A Automated Soil CO2 Flux System provides researchers sophisticated flux monitoring instrumentation in a dedicated system that is modular and easy to use. The System offers options of two short-term survey and two long-term chambers, in addition to the ability to multiplex up to 16 long-term chambers. LI-COR’s research in this area has resulted in better comprehension of soil CO2 flux measurement problems and system design requirements.
The 7460 Series Portable Analyzers are available in six versions for the simultaneous measurement of the gases typically found in the exhaust from internal combustion engines. CO, CO2, and HC's are detected by a dual-wavelength infrared detector. O2 and NOx (as NO) are detected by customer-replaceable electrochemical sensors. If NO2 analysis is selected, this is also by electro-chemical sensor.
The Vapro osmometer is an advanced electronic adaptation of the hygrometric method of vapor pressure determination. The sensitive thermocouple and sophisticated electronics provide the means to measure the dew point temperature depression of a specimen with resolution to 0.00031 °C. Vapor pressure and freezing point are among the colligative properties of a solution.
