New analytical instrument unites 3 measuring tasks in 1 instrument

The new instru­ment ana­lyzes liq­uid, translu­cent sam­ples for their opti­cal spec­trum, col­or, and water para­me­ters. Or any of the three. Oper­a­tors speed up their process­es and improve the qual­i­ty of the results using Easy VIS. They, there­fore, save mon­ey, time, and space.

The com­pact Easy VIS by Met­tler Tole­do effi­cient­ly ana­lyzes flu­id and translu­cent sam­ples. As a true all-rounder, it cov­ers three mea­sur­ing tasks in one instrument.

The instru­ment takes over the mea­sur­ing tasks of up to three instru­ments: a col­orime­ter, a spec­tropho­tome­ter, and spe­cial mea­sur­ing meth­ods for water test­ing, such as titra­tion. All this pow­er rests in one instru­ment about the size of a note­book. The results appear on screen in trust­wor­thy accu­ra­cy, pre­ci­sion, and repeata­bil­i­ty – with­in sec­onds. That saves mon­ey, time, and space. The instrument’s name is Easy VIS, one of the next-gen­er­a­tion Easy­Plus UV/VIS spec­tropho­tome­ters pro­duced by Met­tler Toledo.

Ease of use in a new dimen­sion: Clos­ing the lid of the Easy VIS spec­tropho­tome­ter pro­duced by Met­tler Tole­do auto­mat­i­cal­ly starts the measurement.

Man­u­fac­tur­ers ben­e­fit in many ways

A typ­i­cal place for Easy VIS is the QC lab at small man­u­fac­tur­ers in the food and bev­er­age indus­try, envi­ron­men­tal test­ing labs, or any indus­try need­ing qual­i­ty con­trol and super­vis­ing their process- or waste­waters. The Easy VIS is used dur­ing mul­ti­ple steps of the pro­duc­tion process: For inspec­tion of raw mate­ri­als, qual­i­ty con­trol of semi-fin­ished and fin­ished prod­ucts, or test­ing the water qual­i­ty of wastewater.

This stream­lines the pro­duc­tion process­es con­sid­er­ably. Those who used to send their sam­ples to an exter­nal lab­o­ra­to­ry prof­it even more, as they can now ana­lyze most sam­ples inde­pen­dent­ly at an inter­nal cost.

The visu­al user inter­face with work­flow guid­ance allows you to sim­ply scan and mea­sure. Even untrained staff can oper­ate Easy VIS intu­itive­ly. This increas­es the integri­ty and repeata­bil­i­ty of the analy­sis and saves train­ing time.

Easy VIS oper­ates with­in a wave­length range of 330 to 1,000 nm. The light source is an easy-to-replace tung­sten lamp, which any oper­a­tor can replace with­in no time.

The part­ner device, Easy UV, cov­ers the full UV/Vis spec­trum with a wave­length range from 190 to 1,000 nm to cov­er addi­tion­al appli­ca­tions in the UV range. Plus: The Easy UV runs with a pow­er-sav­ing and main­te­nance-free xenon-flash lamp.

Ana­lyt­ic pre­ci­sion in three fields of expertise

25 stan­dard-com­pli­ant col­or scales in the vis­i­ble range come pre-installed and can eas­i­ly be used. Some exam­ples are ICUMSA for sug­ar col­or, ESBC for beer qual­i­ty analy­sis, or OIV CIELab for wine col­or deter­mi­na­tion. The results reveal the qual­i­ty of the prod­uct with­in seconds.

Water analy­sis shows, for exam­ple, the con­cen­tra­tion of Alu­minum, Ozone, Chlo­rine, or Polyphe­nol. This reveals whether the water is fit for human con­sump­tion or can be used in fur­ther pro­duc­tion. Is the waste­water safe to release? With its numer­ous built-in water test­ing meth­ods, the spec­tropho­tome­ter can quick­ly pro­vide the answer.

For spec­tropho­tom­e­try, the sam­ple is ana­lyzed at the wave­lengths where the sam­ple has its char­ac­ter­is­tic absorp­tion of light. The Easy VIS mea­sures the trans­mit­ted or absorbed light and the read­ing reveals the sample’s con­cen­tra­tion or purity.

The PathDe­tect func­tion of the com­pact Easy VIS spec­tropho­tome­ter pro­duced by Met­tler Tole­do rec­og­nizes which path length is mea­sured and reduces errors.

A typ­i­cal analy­sis with the Easy VIS

The test­ing pro­ce­dure is very sim­ple: One cuvette holds the blank mea­sure­ment, and anoth­er is pre­pared with the sam­ple. After choos­ing the desired analy­sis method, the cuvette is placed in the cuvette hold­er. The PathDe­tect func­tion rec­og­nizes which path length is mea­sured. Clos­ing the lid auto­mat­i­cal­ly starts the blank mea­sure­ment. (By the way, the blank mea­sure­ment is stored for sev­en days. So, this step can be neglect­ed dur­ing the rest of the week unless the mea­sure­ment para­me­ters change). After deter­min­ing the blank, the sam­ple cuvette is brought into the mea­sur­ing posi­tion. The mea­sure­ment starts again auto­mat­i­cal­ly after clos­ing the lid. With­in sec­onds, the results show up on the screen. Now Easy VIS is free to ana­lyze oth­er sam­ples or to start a dif­fer­ent analy­sis method. With the Easy­Di­rect soft­ware, these results may be auto­mat­i­cal­ly saved or export­ed to an exter­nal stor­age device or exchanged with a data man­age­ment sys­tem (for exam­ple LIMS).

Con­clu­sion

Easy VIS has the poten­tial to replace up to three oth­er instru­ments, per­form­ing col­or mea­sure­ment, water analy­sis, and spec­tropho­tom­e­try. It does so with trust­ed accu­ra­cy and pre­ci­sion – with­in sev­er­al steps of the pro­duc­tion process. All this saves mon­ey, time, and space.

Good to know

Met­tler Toledo’s new Easy­Plus instru­ment line embraces the Easy VIS and Easy UV spec­tropho­tome­ter. Both instru­ments offer equal ben­e­fits to their oper­a­tors in accu­ra­cy, speed, and com­pact­ness. They dif­fer in two aspects: wave­length range and light source. The Easy UV is of spe­cial inter­est to those work­ing with­in the UV range from 190 to 1,000 nm. Its xenon-flash lamp is main­te­nance-free and requires no changing.
