A cost effective process analyzer. Its sample system can be designed for either automated dilution or very dirty sample streams. Both titration and ion selective measurements can be done in the same unit. HANDYChem is suitable for analyses in the following industries:

Measurement Methods
Two types of measurement methods are used for almost all NEXTChem analyzers: titration and (ion selective) standard addition. Both types of measurements methods can be used on all NEXTChem analyzers at the same time; making each type of analyzer extremely flexible.

Titration
Titration methods involve the addition of a reagent to the sample until an endpoint is detected with an electrode or color probe. Most of the titrations utilized by the NEXTChem Process Analyzers fall with one of five different categories: acid/base, oxidation/reduction, complexation, precipitation, or color.

Standard Addition
Measurements with the Ion Selective Electrodes (ISE) utilize the standard addition method. The standard addition method involves measuring the sample with the ISE before and after a known standard has been added and using the difference in the readings to determine concentration.

Precision Reagent Pump
The heart of a process analyzer is the way reagents are delivered to the measurement cell. With all NEXTChem analyzers precision reagent pumps are used to deliver reagents. Because of the use of advanced stepper motor technology these pumps are very accurate + 0.001 mL. The utilization of a superior seal material makes the precision reagent pump very low maintenance only requiring to be rebuilt once per year.

Ease of Programming
All NEXTChem analyzers use a touchscreen interface to make them very user friendly. The analyzer is programmed in a similar manner to the interaction with a bank ATM. A series of user selected menus are used to program the analyzer. Each number value is programmed with a popup key pad menu. To make the analyzer as cost effective as possible the user interface is displayed in English only.

Filter-Free Operations
The HANDYChem Analyzer like all NEXTChem analyzers are designed to operate FILTER-FREE; this type of sampling INCREASES RELIABILITY and DECEASES MAINTENANCE. To make FILTER-FREE operation possible NEXTChem has created the “self-cleaning valve”. Utilizing the “self-cleaning valve” particles up to <6 mm can be easily handled. Large bore tubing is used to transfer the sample from the sample panel to the measurement cell 1/4” (6 mm) or 3/8” (9mm). Combining the self-cleaning valve with large bore tubing virtual eliminates the possibility of plugging; usually the most important issue in the operation of a process analyzer.

Automated Sample Dilution
The HANDYChem series of analyzers can be configured to measure very high concentrations. This is accomplished by utilizing a dilution measurement cell. The dilution measurement is used with an external sample capture loop (5-30 mL). This allows a sample with up to <2 mm particles to be captured FILTER-FREE and sample burettes are never used.

GSM/SMS Modem
The HANDYChem Analyzer can be equipped with a GSM/SMS Modem. With this modem the analyzer can send alarm messages and data to a specified number of mobile phones automatically. This capability gives the analyzer real-time remote control and access.
