SECTION 611.611 INORGANIC ANALYSIS
Section 611.611 Inorganic Analysis
Analytical methods are from documents incorporated by
reference in Section 611.102. The substantive rules mostly reference these by
a short name Section 611.102(a) defines. Section 611.101 defines other abbreviations.
a) A
certified laboratory must conduct analyses for contaminants in this Section using
the indicated methods or an alternative method the Agency approved under
Section 611.480.
USEPA Technical Notes, incorporated
by reference in Section 611.102, includes
criteria for analyzing arsenic,
barium, beryllium, cadmium, calcium,
chloride, chromium,
copper, lead, nickel, selenium, sodium, sulfate, and thallium with digestion or
directly without digestion, and other analytical procedures.
BOARD NOTE: Because a laboratory
determines MDLs it reports under USEPA 200.7 (94) and USEPA 200.9 (94) using a
2
´
preconcentration step during sample
digestion, MDLs the laboratory determines analyzing samples by direct analysis
(i.e., no sample digestion) are higher. For direct analysis of cadmium and
arsenic using USEPA 200.7 (94) and arsenic using SM 3120 B (89), SM 3120 B
(93), or SM 3120 B (99), it may be necessary to engage in sample
preconcentration using pneumatic nebulization to achieve lower detection
limits. Direct analysis of antimony, lead, and thallium using USEPA 200.9 (94);
antimony and lead using SM 3113 B (89), SM 3113 B (99), or SM 3113 B (10); and
lead using ASTM D3559-96 D, ASTM D3559-03 D, ASTM D3559-08 D, or ASTM D3559-15
D may require preconcentration, unless the laboratory makes multiple in-furnace
depositions.

3) Arsenic
BOARD NOTE: If the laboratory
uses ultrasonic nebulization in determining arsenic using USEPA 200.8 (94), the
arsenic must be in the pentavalent state to provide uniform signal response.
For direct analysis of arsenic with USEPA 200.8 (94) using ultrasonic
nebulization, samples and standards must contain one mg/L of sodium
hypochlorite.

use of "Waters Method D6508, Rev. 2". The Board cited the ASTM
Method D6508-00 (2005). On May 2, 2012 (at 77 Fed. Reg. 26072, 26096-97; in

BOARD NOTE: For cyanide
determinations, the supplier must adjust samples to pH 12 with sodium hydroxide
to pH 12 when collecting them. When a sample needs chilling, the supplier must
ship and store the sample at 4

encourages acidifying samples for metals analysis and that the laboratory acidify,
rather than at the time of sampling if the supplier follows the shipping time
and other instructions in Section 8.3 of USEPA 200.7 (94), USEPA 200.8 (94), or
