CONOSTAN For X-ray fluorescence, atomic absorption, flame emission and emission spectrometric analyses of metals in oils.

Standards To Burn C O N O S T A N metal lo-organic standards are spe­

cially prepared organic sulfonates in an oi l base. They are used extensively in the cal ibrat ion of

instruments for the analysis of metals in oi l or organic solvents. The variety of forms affords convenience as a reference material for individual metals in atomic absorpt ion or blends in emission spectrometr ic analyses.

Reference in this advert isement to p p m means micrograms metal per gram product .

5000 ppm Standards Individual CONOSTAN standards at 5000 p p m

metal in hydrocarbon oi l solut ion are available for each of the fo l lowing elements:

AB Silver

AI Aluminum

Β Boron

Ba Barium

Be Beryllium

Bi Bismuth

Ca Calcium

Cd Cadmium

Co Cobalt

Cr Chromium

Cu Copper

Fe Iron

In Indium

Κ Potassium

La Lanthanum

Li Lithium

Mg Magnesium

Mn Manganese

Mo Molybdenum

Na Sodium

Ni Nickel

Ρ Phosphorus

Pb Lead

Sb Antimony

Si Silicon

Sn Tin

Sr Strontium

Ti Titanium

V Vanadium

W Tungsten

Y Yttrium

Zn Zinc

The matrix oil for these standards is white mineral oil with a 17 cSt viscosity at 100°F and a flash point of 340°F.

Individual CONOSTAN standards provide consis­tent composition and performance. They can be used as a source of individual or multi-element calibrating standards for all types of spectrometric methods of analysis. These standards are readily soluble in ketones as well as aromatic and paraffinic hydrocarbons with­out the aid of solubilizers.

Concentrates The metals listed in the table under 5000 p p m

standards are available as concentrates. The metal con ­tent varies w i th each concentrate. These standards are f lu id and capable of easy b lend ing w i th oil and each other for special b lend requirements. The level of metal in each concentrate is available o n request and ranges f rom 0.5-13%.

Blended Standards C O N O S T A N b lended standards are un ique for the

direct-reading emission spectrometr ic determinat ion of trace metals in o i l .

C O N O S T A N S-12 standards are blends of equal amounts each of the fo l low ing 12 elements: Ag A l Cr Cu Fe M g Na Ni Pb Si Sn Ti

C O N O S T A N S-21 standards are blends of equal amounts of the fo l low ing elements: Ag ΑΙ Β Ba Ca Cd Cr Cu Fe M g M n M o Na Ni Ρ Pb Si Sn Ti V Zn

These elements are b lended to approximately 75 cSt viscosity in a hydrocarbon oi l . They are available at the fo l l ow ing concentrat ions: 900, 500, 300,100, 50, 30 and 10 p p m , packaged in polyethylene bottles.

Mercury, Arsenic, Selenium These metals in oi l are available for reference

standards at 100 p p m . The reliability of these standards is comparable to the 5000 p p m series, but cont ro l anal­yses are run by methods appropr iate to the low levels at wh ich they are used.

Quality CONOSTAN standards are compatible w i th each

other in any oi l w i t hou t the need for solubilizers. CONOSTAN standards are relatively stable. Some

di lute solutions do need a stabilizer, wh ich is available w i th the standards requi r ing it. For details, you should contact the CONOSTAN Division.

Freeze-thaw tests on b lended CONOSTAN stand­ards show no problems on storage between -40°F and 150°F.

CONOSTAN standards are nonvolatile, being made in oils having a m i n i m u m of 340°F flash point .

C O N O S T A N standards are soluble in ketones as wel l as all hydrocarbons.
