Precolumn Amino Acid Analyzer OPA
modular amino acid analyzer system with automated precolumn OPA derivatization, optimized for the separation of physiological fluids with up to 30 AA
Ortho-phthaldialdehyde (OPA) is the most widely used fluorescent marker for amino acid analysis and can be used for completely automated analysis of protein hydrolysates as well as physiological fluids. The detection limit for primary amino acids is as low as 0.5 pmol, 20 times better than the ninhydrin method (secondary amino acids are not detected).
The system A0426-1 is identical to A0426 but is additionally optimized for the analysis of physiological fluids with more than 30 amino acids. This system is equipped with a more sophisticated autosampler for increased flexibility in derivatization and also features a separate column oven.
The consumables kit Y1000 contains all of the buffers, salts and reagents (in powder form) required for both A0426 and A0426-1.

HI 2300 performs EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature measurements. The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample.
All measurements can be temperature compensated at 20 or 25°C and the compensation coefficient is selectable by the user. The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage directy proportional to conductivity.
The GLP feature allows users to store and recall data about system status.

Biochemical oxygen demand BOD determination is still one of the most important parameters in water resource management. It can be used to evaluate the impact of biodegradable substances in waters and waster water. With its OxiTop® systems, WTW offers a unique, modular and mercury-free instrument system. It is not only suitable for BOD determination, but also for measuring biodegradability and depletion.
In the course of growing environmental consciousness, microbiological degradability tests have become increasingly important. These can be, for example, soil surveys from waste sites or environmental impact surveys for new chemical substances. The necessary respiration measurements for anaerobic or aerobic degradation can be easily carried out using the OxiTop®-C systems with excellent analysis. WTW offers a wide range of application specific packages with appropriate sample vessels.
The advantages of OxiTop® and OxiTop® Control: simple operation, improved controllability and non-toxicity, and measuring ranges of up to 400 000 mg/l BOD (with OxiTop® Control OC 110). As the measured pressure is automatically converted the values can be directly read as mg/l BOD

ATI Models Q45H62 and Q45H63 are reagentless and designed for on-line monitoring and control of chlorination systems. It is available in two versions: a free chlorine monitor for drinking water and cooling water, and a combined chlorine monitor ideally suited for “chloraminated” drinking water. The combined chlorine system can also be used in wastewater effluents where sufficient ammonia is present prior to chlorination to result in a predominantly monochloramine residual. Unlike on-line colorimetric and most amperometric monitors, Q45H systems utilize a membrane-covered polarographic sensor that does not require the addition of chemical reagents. The Q45H system has no moving parts, so there are no pumps or motors that burn out or tubing breaks that create maintenance nightmares. All normal maintenance items are included with each system.

Smaller and lighter than our full size 3700 portable, the 3700C uses the same controller. The 3700C will easily pass through an 18-inch diameter or offset manhole.
Bottle choices with the 3700C are more limited than with the full-size model. The bottle options are: 24 polyethylene 500 ml bottles; a single 2.5 gallon (9.5 liter) polyethylene or glass bottle; or a single 2.0 gallon (7.5 liter) ProPak bag with holder. When using the 24-bottle configuration, the 3700C's bottle carrier makes bottle changes fast and easy.
The exclusive LD90 gives you automatic compensation for changes in head height, plus automatic suction line rinsing to prevent cross contamination. The non-contacting liquid sensor is not affected by conductivity, viscosity, temperature, or liquid composition. There are no internal tubing connections, so cleaning and tubing replacement are fast and easy. The 3700 pump outperforms most competing samplers and maintains the EPA-recommended 2 ft/second line velocity at head heights up to 16 feet, with 1/4-inch suction line. For higher lifts, we recommend our 6700 Series.

Speedmax 400i
Speedmax® is an inline speed of sound measuring instrument for online determining of the concentration of liquid media. Speedmax® is especially suited for measuring dynamic processes in closed pipes of an automation environment. With the measured speed of sound and the temperature of the medium the current concentration of medium can be determined on basis of well known speed of sound curves.
Speedmax® is especially suited for quality assurance, to control continuous processes and min./max.limits in pipes. All parts having contact to the medium are PFA (New Teflon). Therefore Speedmax® can be used for very alkaline, very toxic and/or very aggressive media like concentrated acids and leaches. The measuring values of speed of sound and temperature are measured from outside through the measuring pipe. Process connections are free of seals using flare technology or NPT-screwing.
The design of the pipe minimizes dead volumes over the whole geometry. For output of measuring values a current output, limit outputs and a RS 485 interface are available.

Walchem’s WCU410 Copper Controller and WNI Nickel Controller are optoelectronic on-line analyzers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applications including electroless plating baths and microeth baths (including oxide-replacement types).
The WCU410 may be switched from electroless copper to microetch via the menu, eliminating the need for a second controller. It reduces the need for manual titration, improves yield, and in microetch applications improves productivity by reducing the frequency of bath change-outs.
The WNI410 is available as nickel-only, or with a pH control option which may be added in the field. Two separate pump outputs for nickel and reducer and another for pH are used, each of which is capable of totalizing either pump on-time, volume pumped, or metal turnovers.
Integrated datalogging is available to validate system performance. A USB memory stick is all that’s needed to extract data and event logs that include copper or nickel measurements, and relay status. Download logs from the USB stick to a PC at your convenience. It couldn’t be easier!

The total TDS is a mass estimate and is dependent on the mix of chemical species as well as the concentration while conductivity is only dependent on the concentration of chemical species. Some applications require the measurement of Total Dissolved Solids (TDS) in mg/L, parts per million (ppm) or parts per thousand (ppt). The TDS concentration can be obtained by multiplying the conductivity
value with a factor which is empirically determined. Eutech offers meters that allow the direct reading
of TDS values. These include the TDSTestr™ series, EcoScan TDS 6, CyberScan Standard Portables CON 11, CON 110 and Waterproof Portable CON 410. Bench meters for advanced level laboratory research are the CyberScan CON 510, CON 1500 and colour touchscreen research-grade CON 6000.
